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.

Control Strategy for Atrial Fibrillation

  • Lenient heart rate (HR) control, compared to strict HR control, may be beneficial in patients with persistent atrial fibrillation who have stable ventricular function (left ventricular [LV] ejection fraction >0.40) and/or no symptoms related to atrial fibrillation
    • LV function should be monitored in these patients
    • Lenient HR control is defined as achieving resting HR <110 beats per minute (bpm); strict HR control is <80 bpm at rest and HR <110 bpm during a 6-minute walk
  • One trial revealed that in patients with atrial fibrillation and systolic heart failure, routine strategy of rhythm control is not beneficial compared to rate control strategy

Only 10 percent of patients in this study show an association between ST elevation (STE) in lead augmented vector right (aVR) with multilead ST depression and acutely thrombotic coronary occlusion. Thus, routine STE myocardial infarction (STEMI) activation in STE-aVR is not required for emergent revascularization, but urgent catheterization appears to be essential.

The trade-off between the risk of ischaemic vs bleeding events may be different between Asian and non-Asian patients, which warrants careful consideration when deciding on the duration of antiplatelet therapy following a percutaneous coronary intervention (PCI), according to a presentation at ESC Asia Congress 2019.

Variations in systolic blood pressure (SBP) in the first 24 hours after admission appear to be linked to outcomes in patients with acute spontaneous subarachnoid haemorrhage, a recent study has found.
