In this cardiology-focused lecture, we explore the essential role of cardiac pacemakers — medical devices used to regulate abnormal heart rhythms. Learn how pacemakers work, when they are implanted, and the types used in clinical cardiology today.

???? What’s covered in this video:

What is a Pacemaker and why it’s used

How pacemakers work:
• Electrical impulses and heart rhythm control
• On-demand pacing and heart activity sensing

Components:
• Pulse generator (battery and circuitry)
• Leads and electrodes

Types of pacemakers:

Temporary pacemakers (short-term use)

Permanent pacemakers

Biventricular pacemakers (for heart failure)

Rate-responsive pacemakers (adapt to activity)

Indications for pacemaker implantation:
• Bradycardia (slow heart rate)
• Tachyarrhythmias
• Heart block
• Sick sinus syndrome
• Heart failure requiring synchronization
