Normal sinus rhythm characteristics
In humans, for an ECG to be described as showing a sinus rhythm, the shape of the P wave in each of the 12 standard ECG leads should be consistent with a "typical P vector" of +50° to +80°. This means that the P wave should be: • always positive in lead I, lead II, and aVF • always negative in lead aVR Web11 de abr. de 2024 · Clinical characteristics of patients.
