High Quality Healthcare and Medical Advice


Dr Oliver Segal, Consultant Cardiologist & Electrophysiologist

City of London Medical Centre is proud to be able to offer a range of cardiac services for the diagnosis and treatment of patients experiencing palpitations, atrial fibrillation, ‘funny turns’, faints or other cardiological symptoms such as chest pain and breathlessness. Our cardiac services are led by renowned Consultant Cardiologist & Electrophysiologist, Dr Oliver Segal, who is now available to see patients at our convenient City location.

Latest cardiac innovations – Medtronic Linq device

As well as consultations, Dr Segal will be able to implant the new Medtronic Linq device, to help diagnose patients experiencing infrequent palpitations, atrial fibrillation, ‘funny turns’, black-outs or syncope. The device is the smallest implantable heart monitor in the world (the size of two matchsticks), and replaces the older Reveal XT monitor, which was the size of a memory stick. This new device is able to record a single lead ECG for up to three years. It automatically detects episodes of profound bradycardia (slow heart rhythms), tachycardia (fast heart rhythms) or atrial fibrillation (an irregular heart rhythm) and transmits these wirelessly to a secure website which is accessible only by Dr Segal. The device is used to diagnose causes of palpitations or syncope, to detect AF or to confirm success after treatments such as catheter ablation. The device is safe for use in MRI scanners.

The Medtronic Linq is injected under local anaesthetic via a small incision in the lower left chest using an implant tool, which takes less than a minute. Unlike the old device, this new tiny monitor can be implanted in a procedure room as an outpatient and the device is not visible. Once inserted, the new device communicates wirelessly to its home port, called a ‘My CareLink’ monitor.

The MyCareLink monitor will work anywhere in the world where there is a 3G mobile phone network, so patients can still be monitored on holiday or if travelling abroad on business. If abnormal heart rhythm data is detected, it is transmitted from the Linq to the MyCareLink monitor automatically every night and then to the CareLink web portal over a secure internet connection. Automatic transmissions simply require the patient to be within 2m of the monitor.

Serious events, such as profoundslow or fast heart rhythms, will generate an email alert to Dr Segal 24 hours a day, 7 days a week. Patients can also send information at other times. For example if patients experience symptoms, information can easily be sent with instructions using the monitor’s digital display, which guides the transmission process and confirms information has been sent correctly.
