Various Pacemakers And Their Indications

• Sinus node dysfunction without AV block, without compromised intraventricular conduction and with normal chronotropic function

• Sinus node dysfunction without AV block but with chronotropic incompetence but normal dromotropic function

• Chronic atrial fibrillation with intermittent AV block

• Atrial fibrillation with high grade AV block resulting in chronotropic incompetence

• Sinus node dysfunction with intact AV conduction but potential for AV block;
• chronotropic competence during exercise
• Bradycardia-tachycardia syndrome
• Hypersensitive carotid sinus syndrome – use rate hysteresis
• Malignant vasovagal syndrome – use rate hysteresis with Rest Rate

• Sinus node dysfunction with chronotropic incompetence and potential AV block
• Bradycardia-tachycardia syndrome on medication for tachyarrhythmia

• Normal sinus node function with high-grade AV block
• Neurocardiogenic syncope (use with rate hysteresis)
• Paroxysmal atrial fibrillation if AF suppression and automatic mode switch algorithms are available

• Normal sinus node function with high-grade AV block
• Sinus node dysfunction with chronotropic incompetence and potential or concomitant AV block
• Paroxysmal atrial fibrillation if AF suppression and automatic mode switch algorithms are available

• High-grade AV block with normal sinus node function

• High-grade AV block with normal sinus node function
