The Cardiology Department provides a wide range of diagnostic invasive and non-invasive procedures while offering dedicated cardiology services for the assessment and treatment of cardiovascular disease. The Department caters for inpatients, outpatients and referrals from GPs, Consultants and other hospitals for cardiology assessment and evaluation.
The Department includes a team of seven expert Cardiologists who have a variety of sub specialisation and interests to ensure the breath and depth of the services that the department provides. The department also includes a team of highly trained Clinical Cardiac Physiologists and ecg technicians to ensure rapid analysis, diagnosis and treatment of a variety of heart conditions.
The team works very closely with the Cardiac Cath Lab and St Brigid’s Cardiac Ward in the development of existing cardiac services and the expansion of new ones bringing the department to the forefront of cardiac care nationally.
The cardiology team at Bon Secours Dublin undertake Ambulatory Blood Pressure (BP) monitoring which is a non-invasive method to obtain blood pressure recordings over a 24 hour or 48 hour period. It involves wearing a small cuff around the arm which is then attached to a small monitoring device worn on a belt.The cuff will automatically inflate at regular intervals throughout the 24 hour period. Throughout the day this will be every 20 minutes and after 10pm this will be hourly.
This consistent and regular interval monitoring allows ‘white coat hypertension’ to be eliminated when blood pressure can increase due to being in a medical environment and also for hypertension to be measured effectively. Results can determine if medication intervention is required to control blood pressure and also to evaluate the effectiveness of current medication.
You are advised to continue with your regular day so a true 24 hour review can be obtained. Once the monitor is returned, the measurements are downloaded and reviewed in the Cardiology Department.
The results will be sent directly to your referring doctor.
The carotid doppler ultrasound is used to evaluate the blood flow through the carotid arteries and to check for narrowing of the arteries. The narrowing of the arteries could indicated a potential risk of a stroke occurring and is generally caused by a build up of fat, cholesterol, calcium and other substances that circulate around the blood stream. Early detection of narrowed carotid arteries enables doctors to begin treatments that will decrease the risk of a stroke occurring.
Your doctor may recommend that you complete the scan if you have high blood pressure, diabetes, high cholesterol, family history of heart disease or stroke, have suffered a recent TIA or stroke
The examination is totally painless and will not require any specific preparation. The sonographer carries out with test with a small hand held device called a transducer.
The ultrasound usually takes about 30 minutes to complete.
Bi-ventricular Defibrillator (CRT-D) and Pacemaker (CRT-P) follow-ups are performed the morning after implant, generally 6 weeks post-implant and thereafter every 6 months or following a device ‘shock’ (CRT-D only). Bi-V follow-ups are performed by a qualified Clinical Cardiac technician.
During a Bi-V follow-up, the Clinical Cardiac technician/Doctor will communicate with the device via a compatible analyser (PSA) to establish patient/device diagnostics, alter settings, record arrhythmia episodes and test device function. The Clinical Cardiac technician/Doctor will also assess heart failure status according to the device parameters. This appointment lasts 30 minutes.
With Bi-V devices we also perform resychronisation programming to optimise the settings of the device. The objective of this test is to configure the device to provide the best cardiac output using differentiated programmable settings. This test lasts around 45 minutes and involves the Clinical Cardiac technician/Doctor working in conjunction with an echocardiographer to measure cardiac outputs in various device configurations. This protocol ensures the device is working at optimal levels. This is a non-invasive procedure.
An echocardiography is a painless ultrasound scan of the heart designed to examine the chambers, valves and major blood vessels. It is used to screen for hypertension, clots, infections, valve leakages and to check the heart chamber function. Sound waves are passed through the chest wall and ‘bounce’ back from the structures, providing two dimensional images using ultrasound.
No special preparations are required for this test. You will be provided with a gown to wear as all clothing from the waist up must be removed. The test is conducted lying down on a bed with electrodes attached to your shoulders and chest attached with wires. A colourless painless gel is then applied to the chest allowing the technician to take pictures from various areas of your chest. You maybe asked to momentarily hold your breathe as this improves the quality of the pictures. The procedure takes between 15-30 minutes.
The results are sent to the referring GP or Consultant within 48 hours.
An Electrocardiogram (ECG) is a quick and painless way to assess the rate, rhythm and electrical activity of the heart. This allows the physician to check for cardiac arrhythmias, palpitations and also the effectiveness of medication.
It is a simple procedure involving lying down on a bed for 2-5 minutes with 10 electrodes attached to your chest. The print out is reviewed by one of the cardiology team.
A stress or exercise tolerance test is designed to provide information about coronary artery disease, cardiac arrhythmias, possible heart related chest pain, dizziness and shortness of breath.
The test investigates how well the heart functions when it is under pressure through exercise. During the course of exercise, the heart muscles require more oxygen and hence the heart has to pump more blood. The test can show if there is a reduction in blood supply in the arteries that supply the heart itself during exercise. If positive, the test can predict possible ischemia in the heart. It also helps doctors ascertain the mode and level of exercise appropriate for the patient.
If you are coming for the test, you are advised to bring loose clothing or clothing that is suitable for exercise as it will involve walking on a treadmill. Electrodes are attached to the chest and are connected to an ECG machine. They are used to monitor the heart rhythm / wave form and ensure your safety. Blood pressure is also monitored at regular intervals throughout the test. The test generally lasts about 30 minutes all together with up to 15 minutes on the treadmill.
The results are sent to the referring GP or Consultant within 24 hours.
Pacemaker follow-up (both single and dual chamber) is performed the morning after implant, generally 6 weeks post-implant and going forward possibly 6-monthly or annually (depending on patient circumstances). Pacemaker follow-ups are performed by a qualified Clinical Cardiac technician.
During the pacemaker follow-up, the Clinical Cardiac technician/Doctor will communicate with the device via a compatible analyser (PSA) to establish patient/device diagnostics alter pacemaker settings and test device function.
The appointment lasts 30 minutes and gives the patient ample time to ask questions and discuss living with the device.
A stress echo is a derivation of an echocardiogram. The test is used to assess the heart’s function and structures and how well your heart muscles are working to pump blood to your body. It is also used to assess stress or exercise tolerance in patients with known or suspected coronary artery disease, understand better the limits for safe exercise for patients who are entering a cardiac rehabilitation programme or those who are recovering from a cardiac event. It is also used to check the patients cardiac status before undergoing surgery.
There are two possible methods of obtaining the ultrasound images in a stress echo.The heart rate required in this test needs to be elevated which can be done either through exercise on a treadmill or through the administration of drugs such as dobutamine. With both methods, the patient is monitored with ECG and blood pressure recordings with pre-test and post-test echocardiogram measurements.
Tilt testing is performed when patients are experiencing syncope (passing out/fainting), dizziness or unexplained loss of consciousness.
If you are attending for the test, you will be required to lie down, face up on the tilt table bed. ECG electrodes and blood pressure monitoring equipment will be attached by one of our team of cardiac technicians. The bed is then tilted in a heads up position so you will feel slightly leant backwards for 45 minutes and monitored closely. Any changes in blood pressure and heart rate are monitored which may be the cause of the fainting / dizziness episodes. The bed is returned to the horizontal position and monitored closely until your heart rate and blood pressure return to their initial values.
All patients are advised to have a light breakfast or light lunch before attending this test and to avoid caffeine on the day of the test.
