Why aren’t all schools equipped with a defibrillator?

If I had my way, all schools should be equipped with a defibrillator. Although sudden death in young people is rare, it does occur and when it does occur, it destroys lives and costs many, many life years. The terminal heart rhythm disturbance in individuals who die is ventricular fibrillation. There is only one treatment […]

What is an ICD? What does it do?

An ICD stands for an internal cardioverter defibrillator. This is a device that is implanted into the body under local anaesthetic . The patient usually comes in as a day case to have the procedure done and the device lives just under the left collar bone. We make a 5cm incision under the left collar […]

Why is it recommended that elite athletes have both an ECG and an ECHO?

Most people that play sport are evaluated with a simple ECG and a health questionnaire. However, the very elite athletes normally undergo an ECG and an echocardiogram. To be quite honest, ECG alone is inferior to an ECG and a cardiac ultrasound. The ECG alone will exclude important electrical faults of the heart but will […]

Would the ECHO pick up anything the ECG would miss?

The ECG is very good at picking up electrical faults of the heart but the echocardiogram is a much more detailed investigation that looks at structural abnormalities of the heart. So, minor holes in the heart, minor valve problems will be missed by an ECG but will be picked up with an echocardiogram. In my […]

Should I book an ECG and ECHO? Why is there a choice of services at the OMI?

Diagnosing conditions causing sudden cardiac death can result in utilisation of several diagnostic modalities. These can range from something as simple as an ECG to something as complex as an electrophysiological study. The more tests that are performed, the higher the yield of picking up something that causes sudden cardiac death. Let’s just look at […]

Can I book an exercise stress test?

The exercise stress test could be regarded as an important part of screening for cardiac abnormalities. My personal opinion – in young people in whom the commonest cause of sudden death is from the cardiomyopathies or the ion channel diseases, is that an ECG and an echocardiogram alone is enough. However, there are lots of […]

Are there certain sports which are pre-disposed to long QT?

There is certainly a connection between certain sport deaths and long QT syndrome. The most common sporting discipline that is associated with sudden death  in long QT syndrome is swimming. The thought process is that the dive into the water at the beginning of a swimming contest incites an adrenergic surge – that is a […]

What does it mean to be carrier?

There are certain people who are gene carriers for some of the conditions such as hypertrophic cardiomyopathy or long QT syndrome but these individuals do not manifest any of the clinical features, ECG features or echocardiographic features of the condition. These types of individuals are known as obligate carriers. They can, however, pass the gene on […]
