Long QT intervals predispose the patient to an R-on-T phenomenon, wherein the R-wave, representing ventricular depolarization, occurs during the relative refractory period at the end of repolarization (represented by the latter half of the T-wave). An R-on-T can initiate torsades. Sometimes, pathologic T-U waves may be seen in the ECG before ...

Commotio cordis (Latin, "agitation / disruption of the heart") is a rare disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart (the precordial region) at a critical instant during the cycle of a heartbeat. [1]
It is important to note that microshock (or micro-shock) are not IEV [2] defined terms and are not used in any international standard. "Micro-shock" is an otherwise imperceptible electric current applied directly, or in very close proximity, to the heart muscle of sufficient strength, frequency, and duration to cause disruption of normal cardiac function.
In engineering, physics, and chemistry, the study of transport phenomena concerns the exchange of mass, energy, charge, momentum and angular momentum between observed and studied systems.

Should this article not mention the R-on-T phenomenon, which basically is when a PVC ruins the T wave of the preceding beat, usually causing ventricular fibrillation (and thus risk of cardiac arrest and sudden death)? 70.26.71.233 04:35, 8 December 2010 (UTC)
