Left posteroseptal pathway: Positive delta wave and QRS in V1 indicates a left sided pathway. Negative delta wave and QRS in II, III and aVF suggests posteroseptal pathway
Left cardiac sympathetic denervation is useful as a secondary prevention modality to reduce life threatening arrhythmia in patients with LQTS and CPVT.
Loss of expression of PKP2 decreases peak Na current and delayed recovery from inactivation of Na channels, decreasing Na current and conduction velocity, causing conduction block and re-entrant
Early repolarization has been considered as benign ECG change, till a couple of studies published in 2008 in leading journals caught the attention of the cardiovascular fraternity.
