And right ventricular hypertrophy and the abnormal architecture of the right ventricle, can predispose to late arrhythmias and sudden cardiac death in repaired tetralogy of Fallot. That is why they need follow up for arrhythmias. Atrial arrhythmias are also common after TOF repair.

This can be a source of cardiac arrhythmia as well. An important cause of arrhythmias in Ebstein’s anomaly is the presence of a right sided accessory atrioventricular pathway or WPW syndrome. A huge right atrium can also predispose to supraventricular arrhythmias in Ebstein’s anomaly.

QT prolongation and the occurrence of ventricular arrhythmias with exercise are another important aspect of exercise testing in children. Ventricular arrhythmias during exercise can be documented in congenital long QT syndromes as well as in catecholaminergic polymorphic ventricular tachycardia.

Some of them may develop heart failure, arrhythmias, thromboembolic events and even sudden cardiac death rarely. Blood flow into and out of these recesses can provide a spectacular view on colour Doppler echocardiography, almost looking like flames of fire near the apex, in the apical four chamber view.

Cerebrovascular damage can cause cardiac arrhythmias related to disinhibition of right insular cortex with resulting increased sympathetic tone. In that study commonest ECG abnormalites were QTc prolongation followed by brady/tachycardia and then ST segment deviations [3]. References Yamour BJ, Sridharan MR, Rice JF, Flowers NC.

This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. This leads to shortening of action potential duration. With proper precautions, risk can be reduced.

A recent just accepted article in the Journal of American College of Cardiology mentions that compared to thermal ablation, pulsed field ablation more often resulted in atrial arrhythmia burden less than the clinically-significant threshold of 0.1% That was a new analysis of the ADVENT trial [2].

Ventricular tachycardia is a potentially life threatening cardiac arrhythmia. If the rate is very fast, hemodynamic deterioration can occur rapidly. On the ECG, ventricular tachycardia can be defined as three or more ventricular ectopic beats occurring in a sequence at a rate more than 100 per minute.

ECG is recorded periodically during the test in addition to documenting any specific events like arrhythmias. Treadmill Exercise ECG is usually done with a computerized treadmill unit which controls the motor speed of the treadmill as well as monitors the ECG.

Angina is another common symptom due the hypertrophy which causes a coronary supply demand mismatch Symptoms of HCM include syncope/near syncope, which could be precipitated by exertion, hypovolemia, rapid standing, Valsalva manoeuvre, diuretics, vasodilators or arrhythmia. Palpitations can be felt if there are arrhythmias.

Autonomic dysfunction caused by spinal cord injury is associated with abnormalities in blood pressure, heart rate variability, arrhythmias and blunted cardiovascular response to exercise which can limit the capacity to perform physical activity [1].

So when a pressure injection is given into the left ventricle, there is no single jet going to strike the left ventricular wall and stain the left ventricular wall which can cause arrhythmia. The end hole is not directed directly towards the left ventricular wall. Then there are multiple side holes also there.

Another problem with atrial switch operation is that, they are likely to have atrial arrhythmias, and several other problems and the physiology is not exact as in case of arterial switch operation. Long term results are much better than atrial switch operations.

Measurement of QT interval is very important, as QT prolongation can predispose to serious, life threatening ventricular arrhythmias. QT prolongation leads to torsades des pointes, which is a very serious arrhythmia. This represents the ventricular depolarization as well as repolarization. One easy value which I remember is 0.34

It was a multinational study which enrolled patients at risk for sudden death from ventricular arrhythmias and the follow up period was 6 months. None of the deaths in the study were deemed to be arrhythmia related or procedure related. 151 patients completed the 6 month follow up period. of communication tests.
