PVCs are rarely dangerous. Almost everyone has them from time to time. They can be caused by stress, infection, or overuse of caffiene or other stimulants. PVCs may also be an early warning of other problems such as a thyroid disorder or Heart disease. Something to try to be aware of is if the PVCs are perfusing or nonperusing, that is do you have a pulse with these irregular beats? As long as the beats are perfusing there is no risk of your blood pressure being lowered by these missed or irregular beats.
It is seldom life-threatening
Ventricular ectopic beats are easily seen on an electrocardiogram
myocardial infarction
If the person with heart disease is able to find an effective means of controlling ventricular ectopic beats, the outlook is good.
If you hear a heart mumur, this indicates heart valve disease. If the heart rate is irregular it is either atrial fibrillation or ectopic beats, either atrial or ventricular.
There are three types of heart rhythms and they include; Supraventricular arrhythmias,Ventricular arrhythmias,Bradyarrhythmias.
Basically the heart is having extra beats, but it is unclear if those beats are from the atria or ventricles.
premature atrial contractions (PAC)
ventricular fibrillation
Go to the ER right away. Ectopic pregnancy is very dangerous.
Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest. Premature ventricular contractions are common — they occur in many people. They're also called: Premature ventricular complexes Ventricular premature beats Ventricular extrasystoles If you have occasional premature ventricular contractions, but you're otherwise healthy, there's probably no reason for concern, and no need for treatment. If you have frequent premature ventricular contractions or underlying heart disease, you might need treatment.
Ventricular tachycardia-- A rapid heart beat, usually over 100 beats per minute.
because there is av node in the heart that blocks most of the impulse from atria to ventricles.as for eg if there is 300 beats in atria then its blocks and it slow down the impulse so that there will be around 200 beats to ventricles. during ventricular fibrillation there is not any such devices so it directly affects the system as a result bp increases etc that may lead to death.
