AbstractPremature ventricular complexes (PVCs) are common arrhythmias in the clinical setting. PVCs in the structurally normal heart are usually benign, but in the presence of structural heart disease (SHD), they may indicate increased risk of sudden death. High PVC burden may induce cardiomyopathy and left ventricular (LV) dysfunction or worsen underlying cardiomyopathy. Sometimes PVCs may be a marker of underlying pathophysiologic process such as myocarditis. Identification of PVC burden is important, since cardiomyopathy and LV dysfunction can reverse after catheter ablation or pharmacological suppression. This state-of...

Conclusion: Coronary Angiography remains the near gold standard in diagnosing ischemic heart disease but is associated with serious complications like stroke, arrhythmias, acute renal failure, infection, etc. Though Myocardial perfusion imaging cannot replace coronary angiogram, it can be used as a reliable and sensitive non-invasive alternate investigation to diagnose stable ischemic heart disease in high risk individuals who are unwilling for angiogram.

ConclusionRight SCA with congenital absence of the LCA is one of the rarest coronary artery anomalies. In a significant percentage of patients it is associated with ischemia and can be life-threatening. CCTA and MRI are the modalities of choice for diagnosis and risk stratification.ResumoIntroduçãoArtéria coronária única (ACU) sem cardiopatia congénita associada é uma entidade rara. Maioria dos casos é assintomática e achados acidentais, mas podem causar isquémia, insuficiência cardíaca congestiva e morte súbita (MS).Caso clíni...

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

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...

Rationale: Primary aldosteronism (PA) with hypokalemia increases the risk of life-threatening ventricular arrhythmias. Cases of PA with malignant arrhythmia as the first symptom have been reported. The role of severe hypokalemia in triggering malignant ventricular arrhythmia is well documented. However, few cases of PA with mild hypokalemia that presented with life-threatening ventricular tachycardia have been reported. Patient concerns: A 74-year-old man was admitted to our hospital 25 hours after suffering from syncope caused by ventricular tachycardia without chest pain. Electrocardiogram showed ST segment depres...

Authors: Muser D, Santangeli P, Selvanayagam JB, Nucifora G Abstract Ventricular Arrhythmias (VAs) may present with a wide spectrum of clinical manifestations ranging from mildly symptomatic frequent premature ventricular contractions to life-threatening events such as sustained ventricular tachycardia, ventricular fibrillation and sudden cardiac death. Myocardial scar plays a central role in the genesis and maintenance of re-entrant arrhythmias which are commonly associated with SHD such as ischemic heart disease, healed myocarditis and non-ischemic cardiomyopathies. However, the arrhythmogenic substrate may remai...

Written by Pendell MeyersI received a text at 18:13 of an ECG taken several minutes prior, with no clinical information and only the question " De Winters? "Here is the ECG:What would you tell the treating team???I responded at 18:14 PM:" I think it's posterior STEMI (OMI) instead of de Winter. Cath lab immediately is indicated. "I clarified further:" De Winter would need hyperacute T waves (not present here), and would indicate acute occlusion of the territory in the affected leads; so if there was de Winter in anterior leads, that would mean the anterior wall is the one involved. Here we have iso...
