What are the four types of heart block?
AV nodal blocks
- First-degree AV block.
- Second-degree AV block. Type I second-degree AV block (Mobitz I), also known as a Wenckebach block. Type 2 second-degree AV block (Mobitz II) – due to a block in or below the bundle of His.
- Third-degree AV block (complete heart block)
What is the difference between 1st 2nd and 3rd Av blocks?
If patients with 1st or 2nd degree AV block are symptomatic, they may describe palpitations, an irregular heartbeat or the feeling of “missing a beat.” However, patients with type II second degree block or 3rd degree often experience lightheadedness, syncope, angina, shortness of breath, palpitations, and fatigue.
What is the treatment for complete heart block?
Except in the case of AV block caused by medications that can be withdrawn or infections that can be treated, most patients with acquired complete heart block will require a permanent pacemaker or an implantable cardioverter defibrillator (ICD).
Can blockage in heart be removal without surgery?
Through angioplasty, our cardiologists are able to treat patients with blocked or clogged coronary arteries quickly without surgery. During the procedure, a cardiologist threads a balloon-tipped catheter to the site of the narrowed or blocked artery and then inflates the balloon to open the vessel.
What is the prognosis for complete heart block?
The prognosis of patients with complete heart block is generally poor without therapy. Patients with 1st and 2nd degree heart block are usually asymptomatic.
What causes a 1st degree heart block?
Causes. The most common causes of first-degree heart block are an AV nodal disease, enhanced vagal tone (for example in athletes), myocarditis , acute myocardial infarction (especially acute inferior MI), electrolyte disturbances and medication. The medications that most commonly cause first-degree heart block are those…

How many degrees are in a heart block?
The three types of heart block are first degree, second degree, and third degree. First degree is the least severe, and third degree is the most severe. This is true for both congenital and acquired heart block. Doctors use a test called an EKG (electrocardiogram) to help diagnose heart block.
