A 14-year old boy was forced to do numerous squats as a “punishment”. He woke up the next day with severe pain in his legs — and presented to the ED ( E mergency D epartment ). Renal function and serum electrolytes were normal — but CK was markedly elevated , leading to a diagnosis of Rhabdomyolysis. Cardiac monitoring revealed a series of interesting ( albeit asymptomatic ) rhythms, 2 of which are shown below in Figure-1.

Are you tired of being bound to a stationary ECG machine? Are you ready to upgrade to a solution that suits your on-the-go lifestyle? Portable ECG devices are appropriate for usage in a wide range of settings since they are small, lightweight, and conveniently carried in comparison to traditional ECG machines, which are heavy and usually stationary.

I came across this ECG while reading ECGs for Cardiologs in order to train the Cardiologs Deep Convolutional Neural Network. I don't have any clinical information or any other associated ECGs on this case, but wanted to post it here because it is interesting and it is pathognomonic. What is it? This is a proximal LAD Occlusion. First, there are hyperacute T-waves in V2-V4.

Interventional cardiologists have unique needs. The highly specialized nature of cardiology is such that you need special equipment and software to do your best work and improve clinical workflows, staff experience and, ultimately, patient outcomes. A new era of interventional cardiology is here, and with it comes new technologies designed from the ground up to meet the specific clinical burden of cardiology.

The ECG in Figure-1 is from a middle-aged man — who had just received thrombolytic therapy for presumed acute infarction. No other history available. QUESTIONS: How would YOU interpret this ECG? How certain are you of your answer? Figure-1: ECG obtained from a middle-aged man following thrombolytic therapy. ( To improve visualization — I've digitized the original ECG using PMcardio ).

Objective Ideal cardiovascular health (CVH) was developed to promote CVH as a key component of primordial prevention. Mobile short message service (SMS) is useful for improving health behaviours. We aim to test the effectiveness of SMS intervention in women to improve CVH. Methods In a single-blinded, randomised, controlled study, 620 women, aged 35–70 years, without cardiovascular disease, were enrolled in SMS intervention versus no SMS.

One of the hallmarks of the last two years has been the distance that frequently exists between published research and reality. I’m a cardiologist, and the first disconnect that became glaringly obvious very quickly was the impact COVID was having on the heart. As I walked through COVID rooms in the Spring of 2020 trying to hold my breath, I waited for a COVID cardiac tsunami.

Sent by anonymous, written by Pendell Meyers A man in his 60s presented with acute chest pain with diaphoresis. He had received aspirin and nitroglycerin by EMS, with some improvement. His vitals were within normal limits. Here is his triage ECG: 2045: What do you think? The ECG is subtle, but diagnostic of infero-posterior OMI. The QRS is normal, yet in aVL the normal upright small QRS complex is followed by in appropriately large-volume T wave inversion, which is reciprocal to the T waves in l

Objective The onset of new conduction abnormalities requiring permanent pacemaker implantation (PPI) after transcatheter aortic valve implantation (TAVI) is still a relevant adverse event. The main objective of this registry was to identify modifiable procedural risk factors for an improved outcome (lower rate of PPI) after TAVI in patients at high risk of PPI.

This was posted a few years ago. I'm highlighting it again, with comments from Ken Grauer below. This was sent to me by Jason Winter. @JasonWinterECG This is a 36 yo m with h/o TBI and epilepsy. He had a seizure this morning and rolled out of bed unable to get up. There were no injuries and no chest pain and he appeared well. He complained of 3 days of diarrhea and abdominal pain.

Objective Sarcoidosis is over-represented among victims of cardiac arrest. We aimed to establish whether sarcoidosis is associated with out-of-hospital cardiac arrest (OHCA) in the general population. Methods We conducted a nested case–control study in a nationwide cohort of individuals between 1 June 2001 and 31 December 2015 in Denmark. OHCA cases from presumed cardiac causes were matched 1:10 by sex and age on OHCA date with non-OHCA controls from the general population.
