Atrial arrhythmias are an important source of morbidity in adults with congenital heart disease (CHD) and have been linked to sudden death in certain subgroups. Whereas intra-atrial reentrant tachycardia (IART) is the most common arrhythmia, the prevalence of atrial fibrillation (AF) is increasing.

Blood Pressure Many medications used to treat congenital heart disease can affect blood pressure levels. A rapid heartbeat (tachycardia) can increase the workload on your heart, while a slow heartbeat (bradycardia) can cause fatigue and dizziness. Here are some key things for you and your healthcare team should keep an eye on: 1.

Tetralogy of Fallot (TOF) represents the poster child for monomorphic ventricular tachycardia (MVT) in congenital heart disease. Sustained MVT affects approximately 10% of such patients at 30 years after cardiac repair and is inextricably related to the burden of sudden cardiac death (SCD).(1)

Because of this, it is uncommon to see sinus tachycardia with a prolonged PR interval. And I wish I had record of ECG monitoring just before — and during — and just after the rhythm changes from the regular tachycardia in ECG #1 — to the bigeminal rhythm in ECG #2. This is precisely what we see in Figure-6.

Multiple APs, congenital abnormalities and difficulties in catheter manipulation are particularly challenging situations. However, failed AP ablation is often due to a combination of inaccurate mapping and anatomically challenging APs.

If this is in a child, or a young adult, you will think that this is juvenile T inversion and the heart block is congenital complete heart block, in which heart rate is usually better as it is supra Hisian and narrow QRS as junction will be controlling. Instead usually you will have ventricular tachycardia with AV dissociation.
