	Bigeminy - Wikipedia, the free encyclopedia
		Bigeminy is a heart arrhythmia in which heart beats occur in pairs with a pause between each pair.
		A typical example is ventricular bigeminy which is a normal beat followed by a premature ventricular beat, also known as a premature ventricular contraction (PVC).
		The continuation of this pairing of beats is an example of bigeminy.

	CHEST: Mechanism of bradycardia-dependent appearance of manifest extrasystoles in concealed ventricular trigeminy (Site not responding. Last check: 2007-10-20)
		The mechanism was satisfactorily explained, using the concepts of longitudinal dissociation and concealed 3:2 Wenckebach periodicity in the reentrant pathway of extrasytoles.
		In concealed bigeminy, the number of sinus QRS complexes intervening between two successive extrasystoles is ordinarily uneven (ie, 2n-1);(1)(2)(3) in concealed trigeminy, that number is ordinarily 3n-1,(1)(2)(3) where n is any positive integer.
		On the other hand, bradycardia-dependent appearance of manifest extrasystoles in concealed bigeminy was reported in a case of the classic form(6) and in two cases of the even-number variant;(4)(7) however, bradycardia-dependent appearance in concealed trigeminy has never been reported before.

		We tested the hypotheses that epinephrine shortens the duration of arrest following a defibrillator shock, and that epinephrine increases the occurrence of a secondary arrhythmia (bigeminy).
		Isolated cardiomyocytes from 10-day-old chicken embryos were tissue cultured and in a shaker bath that did not allow the cells to settle.
		Bigeminy occurred more frequently in the epinephrine treated subjects (37.5±13% vs. 24±12%), but not with a 95% confidence interval.

	Medical Mutual Insurance Company of Maine: Beacon June 2005, Pulmonary or Cardiac? (Site not responding. Last check: 2007-10-20)
		The ED physician examined the patient and performed a repeat EKG, which was read as showing sinus rhythm with premature ventricular contractions in a bigeminy pattern.
		However, the EKG showed a new bigeminy pattern when compared to a prior EKG study.
		In light of the patient’s history of a prior MI and tobacco abuse, the final question was whether the usually benign bigeminy pattern might have been a red flag for ischemia – which in retrospect was likely the case.

	Bigeminy
		I have had a difficult time capturing them on an event recorder, but was told it was probably bigeminy.
		Bigeminy in persons with an otherwise normal heart is not considered dangerous.
		I have been told by cardiologists and electrophysiologist that in the setting of a normal heart, their prognosis is no different than that of isolated PVCs or several PVCs a minute, just a bit more uncomfortable.

		Mar 26 2002, 12:40 PM Heartdancer, you sound just like me. andnbsp;I have had this King of Hearts continuous loop event monitor going on three weeks and have been able to record one event and that was after I had stuffed myself with salty, fatty, yummy pizza.
		I've gone to a restaurant recently while in constant bigeminy and was able to sit there and look very normal...even though I felt very abnormal.
		Once a couple of hours passes andnbsp;without bigeminy then the anxiety is gone for the most part.
