The most probable mechanism for post tachycardia troponin rising might be the shortening of diastole with subsequent subendocardial ischemia (6).
Ventricular tachycardia is a fast or rapid heart rate that starts in the heart's lower chambers.
This increased impedance signal is perceived by the pacemaker as increased minute ventilation, which causes the ensuing tachycardia at the pre-programmed rate (3).

For example, palpitations that are regular and paroxysmal in nature, with abrupt onset and cessation or termination of symptoms with vagal maneuvers, are suggestive of atrioventricular reciprocating tachycardia (AVRT) or AV nodal reciprocating tachycardia (AVNRT).
