A member asked:

Hr 55 ecg showed a quick beat after the previous beat and felt a flutter then back to 55. not pvc was normal wave formation?

A doctor has provided 1 answer

Hard to say: Could be a premature atrial contraction (a PAC), or possibly a normal sinus beat in a sinus arrhythmia (a somewhat variable heart beat in an otherwise normal rhythm). Neither of those is generally a concern, but neither is typically symptomatic either. I would check in with your MD, or whoever did the ECG.
