Ganglionic Blockers · Pharmacology

Which effect on heart rate is expected after administration of ganglionic blockers?

  1. Marked bradycardia due to vagal stimulation
  2. Tachycardia due to loss of parasympathetic tone
  3. No significant change in resting heart rate
  4. Ventricular arrhythmias with prolonged QT interval
Show answer and explanation

Correct answer: Tachycardia due to loss of parasympathetic tone

Parasympathetic tone normally slows the heart. When ganglionic blockers inhibit parasympathetic input, the heart rate may increase, resulting in tachycardia.
