Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with symptomatic palpitations described as a "skipped beat" or "thumping" sensation in the chest occurring in a repetitive, rhythmic pattern. Symptoms are consistent with ventricular bigeminy. Patient denies syncope, presyncope, chest pain, or dyspnea. No known history of structural heart disease or recent electrolyte disturbances.
Clinical Examination Findings
Cardiovascular exam reveals a regular rhythm interrupted by frequent premature beats occurring in a bigeminal pattern (one sinus beat followed by one PVC). Heart sounds are S1 and S2 with no murmurs, rubs, or gallops. Peripheral pulses are regular but demonstrate a compensatory pause following the premature beat. No jugular venous distention or peripheral edema noted.
Treatment Protocol
Management plan includes 12-lead ECG to confirm PVC morphology and axis. Order electrolyte panel (K+, Mg2+, Ca2+), TSH, and consider 24-hour Holter monitoring to quantify PVC burden. If symptomatic or if PVC burden is high, initiate beta-blocker therapy (e.g., Metoprolol Succinate). Advise avoidance of caffeine, nicotine, and alcohol. Follow-up scheduled to assess symptom resolution and medication tolerance.
