Vagal stimulation of hea causes? (irrelevant to pharmacology)
Increased hea rate
Increased RR interval in ECG
Increased cardiac output
Increased force of contraction
Increased RR interval is seen in ECG on vagal stimulation. Normal values for waves and intervals are as follows: RR interval: 0.6-1.2 seconds. P wave: 80 milliseconds. ... QT interval: 420 milliseconds or less if the hea rate is 60 beats per minute (bpm) Ref: KD Tripathi 8th ed.
