PVC Frequency

My 20 year old daughter recently had her wisdom teeth extracted when the oral surgeon said that her heart rhythm was abnormal during the first 10 minutes and last 10 minutes of this procedure.  He called it a rhythm of bigeminy.  She had an eco cardiogram done the next day and her heart looks perfectly healthy.  She wore a 24 hour heart monitor and our general practioner said it reported over 800 pvcs in that 24 hour period.  He prescribed metoprolol tartr 25 mg 2x a day and scheduled her to see a cardiologist next week.  I have a few questions... 1) Is this perscription necessary before she is seen by a cardioloigist (I understand it is used to decrease the number of pvc's) 2). What would be considered a dangerouse number of pvc's over a 24 hour period? 3).  What are the side effections of this medication and/or going off this medication?

Side note: As a young child and throughout her life 'occaionally' she has said her heart felt as though it were beating stronger than normal.  She has also had a couple of incidents where she has "as she describes it" someone slowing turning the lights off and she would briefly pass out.  She has always been petite, 5'4" 102 lbs. I'm trying not to stay calm but I'd like to know the severity of this problem.

Thank you for your help.

USES:
This medication is a beta-blocker used to treat chest pain (angina) and high blood pressure. It is also used after an acute heart attack to improve survival. High blood pressure reduction helps prevent strokes, heart attacks and kidney problems.

This drug works by blocking the action of certain natural chemicals in your body such as epinephrine on the heart and blood vessels. This results in a lowering of the heart rate, blood pressure, and strain on the heart.


OTHER USES:
This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This medication may also be used for irregular heartbeats, heart failure, migraine headache prevention, tremors and other conditions as determined by your doctor.


HOW TO USE:
Take this medication by mouth, with or right after a meal, as directed by your doctor. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day.

This drug is not effective if you use it only when chest pain or a migraine headache occurs. It is very important to take this medication regularly as prescribed to help prevent these conditions.

The dosage is based on your medical condition and response to therapy. It may take one or two weeks before the full benefit of this drug takes effect. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick.

Do not suddenly stop taking this medication without consulting your doctor. Your condition may become worse when the drug is suddenly stopped. Refer to the Warning section.

Before having surgery, tell your doctor or dentist that you are taking this medication.

If you have diabetes, this medication may mask the fast/pounding heartbeat you would usually feel when your blood sugar level falls too low (hypoglycemia). Other symptoms of a low blood sugar level such as dizziness or sweating are unaffected by this drug.

This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Limit alcoholic beverages.

To minimize dizziness and lightheadedness, get up slowly when rising from a seated or lying position.

Check the labels on all your medicines (e.g., cough-and-cold products, diet aids, non-steroidal anti-inflammatory drugs-NSAIDs such as indomethacin, ibuprofen) because they may contain ingredients that could increase your heart rate or blood pressure.

carolandtom; one of the questions to ask also is where they are orginating; as this is almost as important as how many and the pattern - trigeminy; bigeminy etc

while 800 pvc's in a 24 hour period may be alarming to you, there are many of us who live and cope with 20,000 - 50,000 pvc's daily; the problem with increasing pvc's is the possibility of developing cardiomyopathy from them - having said that; some of have developed CM and most have recovered or reversed it with medications and/or surgeries

medication prescribed by a doctor shouldn't be stopped unless under the direct care of a doctor just to be safe; check with the cardiologist and since the Echo says her heart looks perfect it my just be something enviromental or chemical like electrolytes causing the pvc's; which she needs to have some blood tests just to check those levels

if she's also had "blackouts" I would recommend you/her metion to the cardiologist a tilt table test TTT or HuTT to rule out certain things

my oldest daughter is almost 24 now and when she was young she would have episodes of blackouts/fainting and I remember the dr saying it was nothing - I've fainted since I was 9 and just found out at 42 that I had something wrong with me; so it's always good to rule out everything to be safe =)
