Heart rhythm definition?
I would like to know the medical language for palpitations which are not due to arrythmias or tachycardia of any form, but simply due to excessive cardiac contraction force
Answer:
"inotropy" describes the amount of force the heart generates next to each heart pulse.
so i guess you could say "increased inotropic force" or "overactive inotropy" or something resembling that. i don't know of any medically diagnostic term for what you've described.
Sinus tachycardia is a heart rate above 120 that originate in the sinus node and propagates in general (not abberantly). It is usually caused by endogenously release epinephrine or noepinephrine. As within fight/flight response or when exercising.
Drugs such as amphetamines and cocaine also can cause sinus tachycardia.
It to some extent depends on the cause. In nonspecific, it's called positive inotropy, or increased myocardial contractility. I don't know the moniker of a chronic condition where the heart beat hard and not nippy. Cardiac glycosides like digoxin (digitalis) are postive inotropes; they increase contractility while slowing the heart rate. A premature ventricular contraction (PVC) can also motive it, because the ventricles have more time to crowd between the PVC and the next overpower. The myocardial fibers stretch, and the heart contracts with more force. That's the grotesque sensation you feel when your heart "skips a beat" and afterwards beats harder afterwards. Look up Starling's Law of the Heart for more detail.
