Written by Pendell Meyers with edits by Steve SmithI was sent these 2 ECGs with no clinical information other than chest pain:Do either or both of these ECGs show ischemic changes? If so, what should you do and why?Let's take them one at a time.What would your response be?I responded: " Awesome classic benign T wave inversion! That's the patient's baseline normal variant. ... But if it were a good story with exertional syncope or something you'd have to treat it like it could be HOCM, etc. Tell me more. "There is sinus rhythm with very large voltage and associated repolarization abnormalities. In V3-V6 there are ...

A 20-something had sudden severe chest pain while smoking marijuana at a party. After approximately 40 minutes, other people there convinced him to call 911. The patient told the medics that he had had this pain on other occasions and it is because of an " enlarged heart. " He denied SOB, N/V, or other recent illness. His vitals signs were relatively normal.The medics recorded a prehospital ECG which could not be found, but they activated the cath lab based on that ECG.On arrival, the patient was very agitated and would not allow any IVs or blood draws.He stated he had a history of pericarditi...

Publication date: Available online 30 November 2016 Source:The Lancet Author(s): Josef Veselka, Nandan S Anavekar, Philippe Charron Hypertrophic obstructive cardiomyopathy is an inherited myocardial disease defined by cardiac hypertrophy (wall thickness ≥15 mm) that is not explained by abnormal loading conditions, and left ventricular obstruction greater than or equal to 30 mm Hg. Typical symptoms include dyspnoea, chest pain, palpitations, and syncope. The diagnosis is usually suspected on clinical examination and confirmed by imaging. Some patients are at increased risk of sudden cardiac death, heart failure, and atr...

CaseThis is a young man who has had chest pain and dyspnea with exertion for years. He presented to the ED with these symptoms again. On this occasion, the CP was associated with stress and accompanied by some SOB, 7/10 at it's worse and made worse with activity, with radiation up into the left side of his neck and face.No h/o hypertension.Here is the ECG:Probable Diagnosis?I was shown this ECG and gave my opinion, as below.Here is an ED bedside echo, parasternal long axis:Look at the small the end-systolic LV chamber sizeParasternal short axis:Again, look at the end-systolic chamber size!What is the Diagnosis?Th...

ConclusionsAlthough intestinal angina is generally defined by severe stenosis of at least two vessels among the celiac and mesenteric arteries, the present case suggests that hemodynamic changes can greatly affect intestinal perfusion and induce intestinal angina in the presence of mild stenosis of the celiac and mesenteric arteries.

LVOT obstruction has multiple deleterious physiological effects including reduction of forward cardiac output, mitral regurgitation of varying degrees, load dependent diastolic dysfunction leading to an increase in LV end-diastolic pressure and coronary flow abnormalities. These factors contribute to symptoms of dyspnoea, chest pain, pre-syncope, and syncope. LVOT obstruction is associated with a greater level of morbidity and mortality within a population of HCM patients and now forms part of accepted risk stratification models for sudden cardiac death in HCM.

Management of supraventricular tachycardia with Wolf Parkinson White syndrome is frequently challenging. A 67-year-old Hispanic male was brought to the emergency department by ambulance with complaints of chest pain and palpitations that began 2 hours prior to arrival. Past medical history included Wolf Parkinson White with accessory pathway ablation, coronary artery disease with single vessel bypass graft surgery, hypertrophic obstructive cardiomyopathy (post-myectomy), aortic valve replacement for aortic stenosis, diabetes mellitus type II, and hypertension.
