The word tachycardia came to English from New Latin as a neoclassical compound built from the combining forms tachy- + -cardia , which are from the Greek ταχύς tachys , "quick, rapid" and καρδία, kardia , "heart". As a matter both of usage choices in the medical literature and of idiom in natural language , the words tachycardia and tachyarrhythmia are usually used interchangeably, or loosely enough that precise differentiation is not explicit. Some careful writers have tried to maintain a logical differentiation between them, which is reflected in major medical dictionaries    and major general dictionaries.    The distinction is that tachycardia be reserved for the rapid heart rate itself, regardless of cause, physiologic or pathologic (that is, from healthy response to exercise or from cardiac arrhythmia ), and that tachyarrhythmia be reserved for the pathologic form (that is, an arrhythmia of the rapid rate type). This is why five of the aforementioned dictionaries do not enter cross-references indicating synonymy between their entries for the two words (as they do elsewhere whenever synonymy is meant), and it is why one of them explicitly specifies that the two words not be confused.  But the prescription will probably never be successfully imposed on general usage , not only because much of the existing medical literature ignores it even when the words stand alone but also because the terms for specific types of arrhythmia (standard collocations of adjectives and noun) are deeply established idiomatically with the tachycardia version as the more commonly used version. Thus SVT is called supraventricular tachycardia more than twice as often as it is called supraventricular tachyarrhythmia; moreover, those two terms are always completely synonymous—in natural language there is no such term as "healthy/physiologic supraventricular tachycardia". The same themes are also true of AVRT and AVNRT . Thus this pair is an example of when a particular prescription (which may have been tenable 50 or 100 years earlier) can no longer be invariably enforced without violating idiom. But the power to differentiate in an idiomatic way is not lost, regardless, because when the specification of physiologic tachycardia is needed, that phrase aptly conveys it.
Sad then that your God is weaker than the devil. I was always taught that he was omnipotent. So can we please stop the God comments cuz this is becoming a religious forum? As many others have stated, myself included, prayer can be a nice form of meditation and i think we can all agree that meditation has a wonderful calming effect that can relax and distract you from the palps. There’s a few common threads in almost every post that i have read:anxiety or some traumatic experience possibly causing PTSD. We all react to anxiety differently so what helps us is going to be different. So if there is no physical reason for your palps, no chemical imbalance, etc then do wh
atever makes you feel better; exercise, pray, meditate, etc. cuz no one else is gonna help you. I go back to my cardiologist on Tuesday and am not expecting a darn positive thing to come out of it. Sad but true.
