hi.i am a student of nursing at TUMS( Tehran University of Medical Sceinses)
can i have ur mail adress tu have communications and sharing ideas about Nursing?
There isn't much research about early PVCs, but here's a good post from the cleveland clinic that sums up

Be careful of the sites you draw facts from when doing searches. Some of them might be very old and misinformed.
R on T manifests as premature ventricular beat occurring in early diastole, and in most cases, it leads to serious ventricular arrhythmia or ventricular fibrillation. I work as a RN in the O.R. and have talked to numerous doctors about R on T. It is still not a well understood phenomenon, however of it happens it almost always ends in a serious arrhythmia. The above post was talking about timing of the PVC , I was simply stating that it would be a good idea to have the focal point and timing of the arrhythmia evaluated. R on T can happen to anyone, a normal person, a heart diseased patient. Im not trying to give bad information, or scare anyone.
Calling R on T pvcs "the deadly PVC" is mis-leading and will cause undue alarm. For someone with an already structurally compromised heart, MI damage, or bad ischemia R on T can lead to Vtach which might degrade into VFib. maybe.
This thread isn't even about R on T so I'm not sure what your intentions are by posting alarming and misleading information.
Fused beats are usually not a problem , or PVC\PAC's in general. However if the PVC falls at a certain point, otherwise known as the deadly "R on T phenomenon", a single PVC can cause your heart to jump straight into V-Fib and cause sudden death. I would ask the doctor more about what types of PVC's you have, the focal point, and the timing of them.
Hi, a fusion beat or fused beat is a PVC.
Technically, it's a "late" PVC. The PVC occurs so late in the cycle that it fuses or becomes part of the P wave on the EKG. They're called fusion beats because it's almost part (or fused) of the next sinus beat.
There are 3 types of PVCs, early, middle, and late. When the PVC occurs affects the pause length and how they feel. In a structurally normal heart I'm not aware of any clinical signifigance to when the PVC occurs. Perhaps someone will be along that knows more than I about them.
