Hello, from your symptom analysis and correlating it with the history that I have gathered from you I feel that you may be having premature ventricular beats (PVB) or premature ventricular contractions (PVC).
If it was CPVT there would be a lot of emotional stress and even flushed appearance and feel due to catecholamine surge.
These are extra beats that happen before a normal heartbeat. The heart is divided into 4 sections, called chambers. PVBs start in 1 of the 2 lower chambers, called the ventricles.
PVBs are caused by a problem with the heart's electrical system, in which the ventricles send abnormal electrical signals. These signals cause the extra beats. VPBs are common. They can happen in healthy people.
Symptoms can be -
●Feeling like the heart is beating hard, beating fast, or seems to skip a beat – These heartbeat changes are called palpitations.
●Feeling dizzy or lightheaded
●A pounding feeling in the neck
You might be more likely to notice PVBs when you lie quietly in bed at night or lie on your left side.
Treatment depends on what is causing the PVBs and whether they cause symptoms. If you do not have symptoms, you might not need any treatment.
Possible treatments include -
●Medicines to control the speed or rhythm of your heartbeat
●A procedure called "ablation" – During this procedure, the doctor uses heat (called "radiofrequency ablation") or cold (called "cryoablation") to destroy the small part of the heart that is sending the abnormal electrical signals. You might have this treatment if medicines do not control PVBs.
