What Causes Heart Palpitations, Lightheadedness, Fainting And Rapid Heart Rate?
I would explain as follows:
Detailed Answer:
Hello!
Welcome and thank you for asking on HCM!
I carefully passed through your question and would explain that your symptoms could be related to extrasystolic arrhythmia as well as a paroxysmal supraventricular arrhythmia (paroxysmal atrial fibrillation or SVT).
Coming to this point I would recommend an ambulatory 24-48 hours ECG monitoring (Holter) and some other tests:
- cardiac ultrasound to examine your cardiac function and structure
- pulmonary function tests for possible pulmonary dysfunction
- complete blood count for anemia
- thyroid hormone levels for possible thyroid dysfunction
- blood electrolytes for possible electrolyte imbalance
- liver and renal function tests
All the above could help to clarify the exact reason of your palpitations and underlying responsible causes.
You should discuss with your doctor on the above issues.
Hope to have been helpful!
Feel free to ask any other questions whenever you need!
Kind regards,

Detailed Answer:
Hi again,
Considering your previously normal health condition and especially cardiac status (confirmed by the previous resting ECG, physical exam and chest X ray study) those supposedly arrhythmic palpitation don't seem to be a serious or life-threatening.
Facing the absence of any known cardiomyopathy, most probably if arrhythmia is present, it is likely to be supreventricular.
Nevertheless, though much less likely, also a short nonsustained ventricular arrhythmia may be possible.
That's why I recommended you the above mentioned tests.
Please, let me know the results of further tests you will decide with your attending physician.
I remain at your disposal for any further uncertainties.
Regards,
Dr. Iliri
Yes, this is possible.

Hello again!
Yes, it is possible for PVCs or supraventricular arrhythmia to cause near fainting and 4 heart palpitations in a row.
Hope you will find this answer helpful!
