HH is one of Dr. Zhang's herbal formulas he recommends in the treatment of Lyme/coinfections.
I know Lyme can mess with the heart rhythm, etc., and many drugs can also cause heart rhythm anomalies as side-effects.
PVC's (and their cousins PAC's - Premature Atrial Contractions) are basically a mis-firing of the electrical signal that triggers a heartbeat, which results in the triggering of a heartbeat too early. The flip-flop sensation (palpitation) in the case of PVC's / PAC's is from the extra-long pause after the premature heartbeat and the next heartbeat, followed by a normal heartbeat but it feels extra strong because of the extra time since the previous heartbeat.
I've had them for years. What I've noticed is some forms of magnesium actually aggravate them for me, and potassium seems to help reduce them...which means there is some magic formula of electrolyte balance that must be involved. Also, I have found a homeopathic remedy helpful for reducing the PVC's ~ this remedy is called Gelsemium. Laying on my left side seems to aggravate mine, so that is something else to keep in mind. Mine were diagnosed when I freaked out one night and went to the ER because my heart rhythm was all wacky (turns out it was a medication side-effect). By the time I got in to see the doctor, the abnormal rhythm was gone but they did see the PVC's on the EKG and told me about them. A cardiologist confirmed the premature heartbeats. An ultrasound of my heart showed no abnormalities, so they told me any medications they could give me would have worse side-effects than just dealing with the PVC's.
Yes, it is good to ask your doctor about the palpitations (palpitations can be a number of things, not just PVC's).
