About an hour so before the person suddenly collapses due to ventricular fibrillation, some people may have these signs and symptoms. Dizziness Nausea Shortness of breath Chest pain and/or tachycardia How do the EKG patterns differ for AFib and VFib? The EKG patterns in most cases are diagnost...
Rapid uncontrolled atrial contractions ( > 300/min) → slower pass through the AV node → uncoordinated ventricular contractions (90–170/min) → tachycardia Decreased cardiac output → stasis of blood → promotes thromboembolism Decreased cardiac output → heart failure Classification[1–4,21] ...

Ventricular fibrillation does not allow the heart to pump enough blood to the arteries, and therefore to the body's vital organs, because the heart's ventricles are quivering (fibrillation), and they cannot pump blood (contract or squeeze). Ventricular fibrillation is considered a medical emergency...
One cardiac arrhythmia is supraventricular tachycardia (SVT). 'Supra-' means above, and '-ventricular' refers to the ventricles. 'Tachy-' means rapid, and '-cardia' refers to the heart. Together, they mean there is a faster than normal heart rate above the ventricles. For example, the atr...

S4153R is a gain-of-function mutation in the cardiac Ca(2+) release channel ryanodine receptor associated with catecholaminergic polymorphic ventricular tachycardia and paroxysmal atrial fibrillation. Can J Cardiol. 2013;29(8):993–6. Article PubMed Google Scholar Franzini-Armstrong C, Protasi F...
So, atrial tachycardia needs to be discussed for recognition and appropriate management. We have gone through different journals to review the latest informations about atrial tachycardia 展开 关键词: Dual AV nodal pathways double ventricular response tachycardia concealed conduction ...
under conditions of increased CaMKII-mediated RyR2 phosphorylation and tissue abnormality in the atria, amplification of the altered RyR2 activation and subsequent diastolic SR Ca2+leakage enhance the susceptibility to pacing-induced AF in the BO group (Fig.5), as in the case of ventricular arrhythmi...
Next, we performed GWAS for all seven LA traits (Table2), and as a sensitivity analysis, we also performed GWAS of LA volumes after indexing on left ventricular end-diastolic volume (Supplementary Materialsand Supplementary Fig.4). For all analyses, linkage disequilibrium score regression intercepts...
