I have a similar problem. I have what they call SVT which is Supraventriclar Tachycardia(heart rate
of over 100bpm). However I also have Nocturnal Bradycardia
(low heart rate of under 60bpm) I am currently on Calcium Channel Blocker
drugs that are used for Angina (I don't have angina). My Echo sonogram slowed that my Bi-cuspid value has an extra leaflet so in stead of having two flaps it has three so technically I have two Tri-cuspid valves. It gives me ectopic beats that feel like my heart is "skipping a beat" but it is actually doing a double beat. The Calcium Channel blockers slow down the heart rate allowing more time for filling consequently a greater blood supply (ie: better preload and therefore a greater afterload). I no longer have the dizzy spells that I was suffering.
causes symptoms at rest. Have you had your Cholesterol
checked lately. Low density lipoproteins
can contribute to the formation of the Atherosclerosis
type plague which forms a scab or cap which can break apart then lead to an embolism. I'm not saying that you have Angina just that it would be worthwhile having it checked. One doesn't need to be overweight to have a cholesterol problem, even skinny people can show signs of Angina. If symptoms persist make an appointment for the cardiologist soon.
