👆At first glance, the ECG looks scary, it looks like some form of regular wide complex tachycardia (regular WCT), but if you look at lead II, you can see that it is spared (green arrows) and does not show regular WCT. Why?
Let me tell you a little secret about lead II, in fact lead II is the only lead in the ECG that does not need electrical inputs from the left arm electrode, every other ECG lead is dependent directly or indirectly (via Wilson’s central terminal) on left arm electrode except lead II, as lead II is dependent only on the inputs coming from right arm and left leg electrodes.
Therefore, any continuous artefact coming from the left arm will be recorded by all 11 leads except lead II, things like tremor in the left arm can produce an artefact in the ECG that look like regular WCT. Spared lead II is a strong and simple observation that will save a lot of thinking and possibly unnecessary actions.
Another observation that strongly suggests an artefact, is that the amplitude of the waves in the limb leads is much larger than that in the chest leads (normally, cardiac electrical events should be more pronounced in the chest leads as the chest leads are more closer to the heart), it means that the source of these large waves is closer to the limbs compared to the heart (left arm tremor).
The waves in the chest leads are about 1/3 that in bipolar limb leads (lead I, II and III), while the waves in the unipolar limb leads (aVR, aVL, and aVF) are about 2/3 that in lead I, II and III. It means that these waves are not coming from the heart.
Let’s analyse lead II (fortunately lead II is the rhythm strip), you can see that the ventricular rate is around 30bpm, while the atrial rate is around 80bpm, and the P waves are upright (suggesting sinus origin) and regular (red arrows), there is clearly AV dissociation, as there is no relation between atrial and ventricular events, therefore, there is complete AV block, and the QRS complexes are either ventricular escape rhythm or junctional escape rhythm with some form of intrventricular conduction delay (I see slightly wide QRS complexes). I support junctional escape rhythm, as the T waves are concordant with the QRS in lead II. Beat #4 is a PVC.
This patient has Parkinson’s disease, knowing that would make the decision much clear and easier, but I avoided mentioning this important note in the presentation to raise the level of the challenge😁
Thank you for reading, I hope the above helps, I learned this from Dr. Ken Grauer, he kindly explained a similar case for me long time ago.

A 72-year-old woman with a history of hypertension presented with an unpleasant awareness of her heartbeat and chest discomfort. On examination, her pulse rate was 30 bpm, with fine basal crackles and distant heart sounds. CXR showed Kerley B lines. One month earlier, she had an episode of palpitations and was diagnosed with paroxysmal atrial fibrillation, for which she was started on flecainide and bisoprolol.
This is a very interesting case. It was originally posted by Dr. Ali A. Rasheed, who kindly explained it to me a year ago.

Sent for CT هذا البيشنت لازم
طبعا ال SAH يجي ب finding of STEMI مو بس cerebral T wave
بالنتيجة المريض اندز CT و فعلا طلع SAH

Very tough one⚡️⚡️⚡️ I would love to hear your interpretation, and learn from you, before I share my thoughts and first impression on this ECG. In fact, this Case was posted by “ECG weekly” on facebook, unfortunately they don’t share the answer with the…
👇This is my thoughts on this ECG
اغلب المرضى (حوالي ٧٠٪) اللي بيحصل لهم DKA مع ال SLG2is، السكر عدهم يكون اقل من ٢٥٠ وجزء كبير منهم السكر يكون اقل من ٢٠٠ (مو لازم السكر يكون مرتفع )
Risk factors of DKA with SGLT2 inhibitors include
Very-low-carbohydrate diets
Prolonged fasting
Dehydration
Excessive alcohol intake

This post is for discussion, and I’d love to hear your thoughts.
We were always taught that thrombolytics are not indicated in patients with Non-STEMI. The usual explanations include that thrombolytics might worsen a partial occlusion into a complete one, or that they could generate emboli that block distal coronary vessels, among other explanations.
What do you think? Why are thrombolytics truly not recommended for patients with Non-STEMI?

Most common cause of HF is IHD
2nd common cause is HT
So Mx. Of HT decrease rate of HF more than 50%
