Heart Blocks Quick Review:
1. 3rd Degree Block Rate: Atrial rate > Ventricular rate Rhythm: Atrial Regular, Ventricular regular. There is no relationship between the P-waves & QRS complexes P waves: Normal in Size & Shape PR interval: NA QRS: Usually Wide (> 0.12 sec) if the block is below the His junction. 2. 1st Degree Block Rate: Usually within normal range Rhythm: Regular P waves: Normal PR interval: Prolonged (> 5 Small boxes; > 0.20 sec) QRS: Usually Narrow (≤ 0.12 sec) 3. 2nd Degree Type 2 Rate: Atrial rate > Ventricular rate Rhythm: Atrial Regular, Ventricular irregular P waves: Normal in Size & Shape PR interval: PR interval stays constant; occasional P waves without QRS QRS: Usually ≥ 0.12 sec with drop QRS complexes 4. 2nd Degree Type 1 Rate: Atrial rate > Ventricular rate Rhythm: Atrial Regular, Ventricular irregular P waves: Normal in Size & Shape PR interval: Progressive lengthening of the PR interval until a beat is dropped (p wave is not followed by a QRS) QRS: Usually Narrow (≤ 0.12 sec) with drop QRS complexes For a short video discussion on Heart Blocks: https://www.youtube.com/watch?v=zk232G5ilro hashtag#TheResuscitationCoachhashtag#heartblockshashtag#ECGhashtag#EKG
