Hi:
The most common type of palpitations, premature ventricular contractions (PVCs, occurs even in many heart-healthy individuals), has various causes or triggers, cardiac and non-cardiac in origin.
As reported, PVCs are typically harmless (benign), be it isolated (single), couplets (2-in-row), triplets (3-in-a-row) or salvos (short bursts of 3 or more in-a-row), bigeminy (occurring every other beat), trigeminy (occurring every third beat), quadrigeminy (occurring every fourth beat), etc., etc.
However, the
main problem or concern (even more so, much more emphasized for those with certain major or serious heart conditions) with PVCs is if/when sustained ventricular tachycardia (runs of PVCs over 30 seconds) occurs.
Non-sustained ventricular tachycardia (runs of PVCs under 30 seconds, but typically not salvos)
may/can become serious as well if it occurs frequently (episodes are grouped closely/tightly together). PVCs may/can occur with/in the presence of bradycardia (heart rate under 60 BPM), tachycardia (heart rate over 100 BPM).
Symptoms that may/can occur wih PVCs includes chest pain/discomfort/pressure/tightness, difficulty breathing, lightheadedness/dizziness, and in uncommon to rare cases, near-syncope or syncope (temporary loss of consciousness, includes fainting and passing out).
Additionally, of the different types of heart conditions, various symptoms may/can be acute (occurring suddenly), be chronic (occurring over a long period of time), come and go (be transient, fleeting or episodic), or even be silent.
ALWAYS be
proactive in your health care and treatment.
Most important,
communicate/interact well with your doctors.
Best of luck down the road of life. Live long and prosper.
Take care,
