Tachycardia or tachyarrhythmia is used to describe the presence of cardiac rhythm abnormality in states when cardiac rate is increased to >100 bpm.
Divided into supraventricular and ventricular tachycardia.
Signs and symptoms related to rapid heart rate are altered sensorium,
angina, shortness of breath, myocardial infarction, hypotension and
other signs of shock (eg cold clammy skin, low urine output), heart
failure or pulmonary congestion.
Bicuspid and tricuspid aortic valve patients have comparable 30-day and 1-year mortality outcomes after transcatheter aortic valve replacement (TAVR), reports a recent meta-analysis. Rates of stroke and new pacemaker implants are likewise similar.
A left ventricular ejection fraction (LVEF) cut-off of 60 percent may identify patients with heart failure (HF) with mid-range or preserved ejection fraction (mrEF or pEF) who could benefit from drug therapy.
