premature ventricular contractions are considered non dangerous by
cardiologists. Basically you are experiencing extra electical signals in
one of the ventricles, usually the left. An ECG is able to easily detect
these instabilities and a cardiologist should be able to distinguish between PVC that can cause sudden death and that which is not dangerous. Most people who have PVC have no symptoms at all and
some people are more atuned to their heart, causing them to experience
palpitations. If the cause is detemined through heart disease for example then medication will be administered to reduce the risk of sudden death, such as beta blockers, ace inhibitors and statins.
For more severe cases, a special pacemaker would be fitted.
So, it really is up to the cardiologist to establish what is causing your
PVC and whether it is dangerous, and then create a plan (if any) to reduce risks. Eliminating caffeine intake, as well as tobacco and alcohol usage (if in your lifestyle) will have a large effect on PVC.
Anxiety attacks are also likely to bring on the symptoms.
There seems to be a huge conflict between cardiologists and patients regarding PVC. While most are not dangerous and require no attention,
patients feel traumatised by the symptoms and feel there is something more seriously wrong.
