It most probably is not SV Tach, because that can be life threatening. And no physician would see that and say it is ok. It was probably Premature Ventricular Contractions or PVC's. Many people have them and are benign. Generally, in nursing they don't want someone to have more than 6 per minute without contacting the doc. It would just indicate some cardiac irritability.But if you have concerns, contact the doc again and tell him of your thoughts.

Definition Return to top
Ectopic heartbeat is an irregularity of the heart rate and heart rhythm involving extra or skipped heartbeats.
Causes, incidence, and risk factors Return to top
Ectopic heartbeats are an arrhythmia involving small variations in an otherwise normal heartbeat. In many cases, they may occur without obvious cause and be benign.
Other times, however, they are associated with electrolyte abnormalities in the blood which should be corrected. They can also be associated with ischemia, or local reduction in blood supply to the heart. In addition, ectopic beats may be caused or aggravated by excessive smoking, alcohol consumption, caffeine, certain medications, and some illicit drugs.
Ectopic beats are rare in children other than those with congenital heart disease. The majority of extra heartbeats in children are PAC's (premature atrial contractions), which are almost always benign.
In adults, ectopic beats can occur more commonly, and underlying reversible reasons should be investigated even if it turns out that no treatment is ultimately needed.
Symptoms Return to top
* the sensation of feeling heart beat (palpitations)
* the sensation of stopped or skipped beats
Note: In many cases, the person may have no symptoms.
Signs and tests Return to top
A physical examination may show an occasional irregularity, but if the ectopic beats do not occur frequently, they may not be detectable on physical exam. Blood pressure is usually normal.
An ectopic heartbeat may be revealed on:
* an ECG
* continuous ambulatory cardiac monitoring (Holter)
Etopic beats may also be observed during:
* an echocardiogram
* coronary angiography
Treatment Return to top
Often ectopic heartbeats do not require treatment. The condition is treated if symptoms are severe or if extra beats are very frequent.
An underlying cause, if discovered, may also require treatment.
Expectations (prognosis) Return to top
Ectopic heartbeats are generally benign, requiring no treatment. Ocasionally, they may indicate an increased risk for other cardiac arrhythmias.
Complications Return to top
* ventricular tachycardia (occasionally)
* other arrhythmias (occasionally)
Note: There usually are no complications.
Calling your health care provider Return to top
Call your health care provider if you feel palpitations that are persistent or are accompanied by chest pain or other symptoms.
Call your health care provider if ectopic heartbeats have been diagnosed and the symptoms worsen or do not improve with treatment.
Prevention Return to top
Moderation in caffeine, alcohol, and tobacco use may reduce the risk of ectopic heartbeats in some people. Exercise often helps persons who lead a sedentary lifestyle.
