Vagally-Mediated Bradycardia Initial treatment for most patients is pharmacological; pacing is indicated for patients unresponsive to pharmacological treatment or with risks factors for asystole. Treatment using drugs If adverse features are present, give atropine 500 mcg IV and, if necessary, repeat every 3–5 min to a total of 3 mg. Doses of atropine of less than 500 mcg can cause paradoxical slowing of the heart rate. Pacemaker implantation should be considered for patients with recurrent vasovagal or situational syncope that is refractory to other therapies. The treatment of specific bradyarrhythmias should be in accordance with the guidelines laid forth by the joint councils of the American Heart Association and the American College of Cardiology. bradyarrhythmia. If transcutaneous pacing is ineffective (eg, inconsistent capture), prepare for transvenous pacing and consider obtain-ing expert consultation.

Appointments 800.659.7822 Currently there is no long term medical therapy for bradyarrhythmias, although isoprenaline or adrenaline is sometimes given in high dependency environments to increase heart rate for patients in extremis while arranging pacing. Treatment Generally, you want a slower heart rate when you’re resting. It’s a sign of good health. But if it’s too slow, it could be a symptom of a condition called bradycardia. Treatment of bradycardia. Borderline or occasional bradycardia may not require treatment.

It is also important to keep in mind that not all cases of cardiogenic syncope are associated with bradycardia.

Low-level evidence suggests that magnesium is effective for rate control (LOE 3) 34 in patients with atrial fibrillation with a rapid ventricular response (LOE 2), 40 so it may be considered for this arrhythmia. Patients presenting with haemodynamic compromise, signs of cerebral hypoperfusion, progressive heart failure, or life-threatening arrhythmias secondary to bradycardia require urgent treatment, including the use of temporary pacing. The treatment of bradycardia is dependent on whether or not the person is stable or unstable. If oxygen saturations are low, supplemental oxygen should be provided.
