62 year old female patient with COPD monitored during aorto-bifemoral graft procedure.
Rhythm analysis indicates normal sinus rhythm (NSR) with a 1st degree heart block.
This encounter displays a P wave of over 200 ms or one square away from the QRS, making it 1st degree heart block. This condition represents a delay between atrial and ventricular conduction. It is not considered dangerous, but can escalate to higher level blocks. The rhythm for this encounter is normal sinus, due to the regular rhythm and presence of P waves.
