Hi:
"Could it be stress related" It may/could be. Stress can cause various symptoms, even wreaking havoc on the entire body.
In general, 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.
Often, 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.
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 none at all or 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,
as applicable, there is a condition commonly known as supraventricular tachycardia (SVT) or paroxsymal supraventricular tachycardia (PSVT), which has various causes (or triggers), though sometimes it can be deemed as "idiopathic", no known cause, cause unknown.
PSVT typically causes a frightening
burst/surge in heart/pulse rate that begins/starts and ends/stops suddenly (hence the term paroxsymal), which can last
for just mere seconds or it can continue on for minutes to hours to days.
SVT is a broad term that includes various forms of an arrhythmia originating above (supra) the ventricles (the heart's lower pumping chambers). SVT can send the heart into speeds
up to 150-200 BPM, and sometimes, even as high as 300 BPM.
SVT/PSVT typically does not damage the heart, is typically not serious or life-threatening in a structurally normal heart, though some symptoms that may/can occur can surely make one feel/think otherwise.
Symptoms that may/can occur with SVT, PSVT includes chest pain/discomfort/pressure/tightness, shortness of breath, lightheadedness/dizziness, and in uncommon to rare cases, syncope (temporary loss of consciousness, which includes passing out or fainting). Sometimes there can be no symptoms at all.
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 (
such as an irregular heartbeat, requiring the use of a Holter monitor or event recorder at home and during daily activities) or even be silent.
Best of luck down the road of life.
