How will you differentiate a wenkebach’s Mobitz type 1 AV block from type 2 second degree AV block if the conduction ratio is 2: by Dr. Sangareddi V. Medical Doctor Posted Wed 11 Nov 2009 10:01pm It is the classical description of wenkebach AV block type 1 there is progressive prolongation of PR interval followed by a blocked p wave and hence a dropped qrs complex. The usual conduction ratio for wenkebach AV block is 3:2 or 4:3 . It is well known wenkebach AV block is usually a benign form of AV conduction defect and it recovers sp ... Read on »
Pseudo Type II Second Degree AV Block Induced by Concealed Premature Junctional Complexes (PJCs) (contributed by K. Wang) by Stephen Smith Posted Mon 26 Aug 2013 1:58pm This patient is running on a treadmill Figure 1. There are frequent apparently non-conducted p-waves.  The PR interval is not lengthening, so this is not AV Wenckebach phenomenon.  It appears to be 2nd degree AV block, Mobitz Type II. The stress test was stopped for fear that it was induced by ischemia. This tracing was a ... Read on »
Intermittent third degree heart block due to stuttering inferior STEMI by Stephen Smith Posted Fri 30 Mar 2012 4:49pm A 71 year old male complained of near syncope and SOB without any chest pain.  His pulse was slow.  He was put on the monitor.  Here is the rhythm strip There is 3rd degree AV block at a rate of 48 A 12 lead ECG was recorded about 5 minutes later Sinus rhythm at a rate of 60, with a normal PR interval, and right ...

What kind of AV block is this?? And where is the coronary occlusion?? by Stephen Smith Posted Tue 31 May 2011 1:16pm A 76 year old male presented with chest pain.  Here is the initial ECG ST segments: There is obvious inferior STEMI, with ST elevation (and Q-waves and T-wave inversion) in II, III, aVF and reciprocal depression in I and aVL.  Where else is there ST elevation?  Where is the occlusion.   Rhythm: slow and regular.  p-waves are not cond ...

How to diagnose complete heart block without ECG ? by Dr. Sangareddi V. Medical Doctor Posted Fri 18 May 2012 12:47pm You are asked to see a patient with a pulse rate of 45 /mt .  Is it sinus bradycardia  or  complete heart block  ?  Only one condition , . . .  you must conclude in the bed side ! Heart rate  may give a clue ( HR of  30-40 is common in CHB . Less common in sinus bradycardia.) Pulse volume is large in both (More so in CHB ) ... Read on »
Unusual presentation of STEMI : Mobitz type 2 AV block by Dr. Sangareddi V. Medical Doctor Posted Wed 18 Apr 2012 1:31pm A 55  year old man came with a BP of  1o0/70 with vague symptoms of back  pain to our ER. Troponin T  was positive Can we thrombolyse ? There is a minimal ST elevation in inferior leads  but not amounting to  the required criteria 1 mm Technically No , Academically yes , scientifically No , logically  yes *I wont t ... Read on »
What is the mechanism of complete AV block in inferior MI ? by Dr. Sangareddi V. Medical Doctor Posted Thu 13 Aug 2009 6:27pm 1 Comment Conduction disturbance is a fairly common occurrence following  MI. Inferior STEMI is especially prone for AV blocks. This is because  the  blood supply to AV nodal  tissues and the inferoposterior surface of the heart  share the same arterial territory . AV node gets it supply  90% of time by right coronary artery(RCA )  and 10% by  LCX. Ver ... Read on »
Bizarre T-wave inversion of Stokes Adams attack (syncope and complete AV block), with alternating RBBB and LBBB by Stephen Smith Posted Fri 19 Aug 2011 1:30pm This is a 68 yo male with a history of aortic stenosis, on carvedilol, fell from a ladder approx 20 ft onto concrete, landing face down with likely loss of consciousness.  Upon EMS arrival, pt was still face down in a pool of blood, but was responsive, alert, and neuro intact.  His BP was stable en route, but he was bradycardic in the 30's. ...

Another interpretation of the last rhythm strip, by Ken Grauer. In any case, no AV Block! by Stephen Smith Posted Wed 01 May 2013 11:44am One very sophisticated reader, Ken Grauer, came up with another interpretation of the last rhythm strip. Here is the strip: Here is K. Wang's ladder diagram and interpretation: Answer: b) NSR and AV junctional acceleration with AV dissociation and occasional capture beats. Discussion. As diagrammed, P waves from th ... Read on »
