Cardiovascular Implantable Electronic Device (CIED) are devices implanted for diagnostic or therapeutic purposes and include pacemaker, ICD, CRT and ILR.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a potentially life threatening cardiac channelopathy with propensity for polymorphic ventricular tachycardia with exercise or emotional stress.

Early repolarization syndrome thought to be benign for long time has been linked with ventricular fibrillation recently.

Silent atrial fibrillation is asymptomatic atrial fibrillation detected by monitoring, either by telemetry or Holter.

Atrial flutter can be classified into isthmus dependent and non-isthmus dependent.

Two independent rhythms on an electrocardiographic recording noted in: "piggy back" transplant, maternal and fetal ECGs, re-recording on same Holter tape.

ECG features of parasystole are: varying coupling interval, inter ectopic interval has a common denominator other than 1 and fusion beats.

Electrophysiological hall mark of intra Hisian block is split His potential.

Post pacing T wave inversion has been called Chatterjee phenomenon and it has been attributed to cardiac memory after an abnormal depolarization sequence.
