Hello dear
We need to understand first what do you mean by ectopic beats. You must have been told either they are APC (atrial
premature beat) or VPC (ventricular premature beat). Calaptin is used to control the
heart rate in those whose heart rate suddenly shoots up more than 160 or for those who have symptoms even when the heart rate is less than that but very irregular. We are not discussing whether calaptin is the right drug or not . What I want you to know is that such medicines need to be taken regularly and not intermittently, to avoid symptoms.
Do not worry about interactions between the
eltroxin and calaptin. For you it is important to know that incase you are planning
pregnancy, your
TSH must be in the normal range.
Second, discuss the need to continue calaptin with your doctor. Calaptin can be used in pregnancy when deemed necessary based on your heart rate issues (to be decided by your treating doctor).
Ectopics are not directly related to hypothyrodism unless you have developed a
heart disease due to uncontrolled
hypothyroidism or untreated hyperthyrodism. Again your treating doctor can tell you if you ever had a related heart disease or this one is unrelated.
So relax and get in touch with your doctor.
Hope this helps.
