  2. Premature ventricular contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_ventricular...

    For patients with more than 1,000 PVCs per day, the risk of developing left ventricular systolic dysfunction after 5 years follow-up is low. Frequent PVCs may increase the risk of developing cardiomyopathy, which can greatly impair heart function. A PVC burden greater than 10% is the minimal threshold for development of PVC-induced cardiomyopathy.

  3. Ectopic beat - Wikipedia

    en.wikipedia.org/wiki/Ectopic_beat

    Ectopic beat is a disturbance of the cardiac rhythm frequently related to the electrical conduction system of the heart, in which beats arise from fibers or group of fibers outside the region in the heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node).

  5. Heart rate turbulence - Wikipedia

    en.wikipedia.org/wiki/Heart_rate_turbulence

    A PVC interrupts the normal cardiac cycle, so the ventricles of the heart do not have time to fill up to their normal level, before contracting and pumping their contents out. This results in a pulse ( blood pressure ) weaker than expected and triggers normal homeostatic mechanisms that try to compensate by constricting arteries and increasing ...

  8. Cardiac Arrhythmia Suppression Trial - Wikipedia

    en.wikipedia.org/wiki/Cardiac_Arrhythmia...

    The second Cardiac Arrhythmia Suppression Trial (CAST II) modified the enrollment criteria to include patients at higher risk for serious arrhythmia. [4] This included 1) patients enrolled within 4 to 90 days of a previous MI, 2) a left ventricular ejection fraction lower than 40%, 3) prior to enrollment, suppression of PVCs had occurred with the drugs (vs. placebo) using a double-blinded ...

  9. Palpitations - Wikipedia

    en.wikipedia.org/wiki/Palpitations

    The rhythm of the palpitations may indicate the etiology of the palpitations (irregular palpitations indicate atrial fibrillation as a source of the palpitations). [1] An irregular pounding sensation in the neck can be caused by the dissociation of mitral valve and tricuspid valve , and the subsequent atria are contracting against a closed ...
