A middle-aged patient called 911 for 1 hour of chest pain.He was hemodynamically stable.Here is the prehospital ECG:Obvious inferior MI, but also with STE in V3-V6Here is the first ED ECG:Again, inferior and lateral STEMI.Is there any right ventricular (RV) MI?85% of inferior MI are due to RCA occlusion.  Even the majority of inferolateral MI are due to RCA occlusion. The RCA may have a large lateral branch.RV MI is caused by RCA occlusion proximal to the RV marginal branch, especially when there are no collaterals from the LAD to the RV.We showed that, if there is zero ST depression in lead V2, that lead V1 is 85% se...

A previously healthy, well-appearing 42-year-old female living in a modern, high-rise apartment in downtown Los Angeles calls 9-1-1 at 5:30 am complaining of worsening of a burning, epigastric pain she had been experiencing for the last three days. She reports associated nausea and non-bloody, non-bilious vomiting, and that she couldn’t manage to get comfortable in bed until she finally decided to call for help at daybreak. During her 9-1-1 call, she reports “pain, like heartburn, that just woke me up again and I had to throw up, … and then I was sweating so much.” Using the Los Angeles Tiered Disp...

A recent residency graduate, let's call her " The Graduate " or " TG, " texted me these ECGs from somewhere far away across the country, in real time, in the hopes of being able to persuade the interventionalist to take the patient to the cath lab.CaseAn otherwise healthy middle-aged patient presented with chest pain of uncertain duration.Here is the initial ED ECG (I apologize for the poor quality of these images -- they were mobile phone photos of computer screens, texted to me -- but they are good enough!):What do you see?There was a second ECG after the patient had symptom resolution:What do you see...

Publication date: Available online 9 January 2019Source: Biosensors and BioelectronicsAuthor(s): Wei Yin Lim, T. Malathi Thevarajah, Boon Tong Goh, Sook Mei KhorAbstractThe early detection of acute myocardial infarction (AMI) upon the onset of chest pain symptoms is crucial for patient survival. However, this detection is challenging, particularly without a persistent elevation of ST-segment reflected in an electrocardiogram or in blood tests. A majority of the available point-of-care testing devices allow accurate and rapid diagnosis of AMI. However, AMI diagnosis is reliable only at intermediate and later stages, with my...

CONCLUSIONS: Non-RF GAS myocarditis typically affects healthy young males and represents about 3% of all hospitalised patients with myocarditis. These patients may be mistakenly diagnosed with an acute rheumatic fever or myocardial infarction. The prognosis in generally good following treatment with antibiotics and possibly NSAIDs.

AbstractAccording to the survey 17.5 million deaths are happened due to the cardiovascular disease that leads to create heart attack, chest pain and stroke. Based on the survey it clearly concludes that most of the people affected by heart problem that need to be identified in the earlier stage for eliminating the future risk in patient health. The importance of the heart disease detection process helps to create the earlier detection system for identifying heart problem by using machine learning and optimized techniques but the developed forecasting systems are difficult to predict the heart problems in an accurate manner...

An elderly man, with history of hypertension and obstructive sleep apnea, woke up with severe chest pain, nausea, and sweating. Upon arrival of the emergency medical team, he had low blood pressure (85/40  mm Hg), with no significant difference between upper limbs, no signs of congestion, and palpable bilateral upper and lower limb pulses. An electrocardiogram (ECG; Figure 1A) was performed, revealing ST-segment elevation in aVR and aVL and diffuse ST-segment depression, which was interpreted as an ST-segment elevation myocardial infarction (STEMI) equivalent.

AbstractChest pain is responsible for 6 –10% of all presentations to acute healthcare providers. Triage is inherently difficult and heavily reliant on the quantification of cardiac Troponin (cTn), as a minority of patients with an ultimate diagnosis of acute myocardial infarction (AMI) present with clear diagnostic features such as ST-e levation on the electrocardiogram. Owing to slow release and disappearance of cTn, many patients require repeat blood testing or present with stable but elevated concentrations of the best available biomarker and are thus caught at the interplay of sensitivity and specificity.We ident...
