An ST elevation is considered significant if the vertical distance inside the ECG trace and the baseline at a point 0.04 seconds after the J-point is at least 0.1 mV (usually representing 1 mm or 1 small square) in a limb lead or 0.2 mV (2 mm or 2 small squares) in a precordial lead. [2] The baseline is either the PR interval or the TP interval ...

The small tortoiseshell butterfly is able to differentiate between various flowers through visual signals. [16] Tortoiseshell butterflies in particular tend to prefer colours at both ends of the visible light spectrum for humans, 400 nm and 600 nm. [17] These correspond to the colours violet and red respectively.

The Holter's most common use is for monitoring ECG heart activity (electrocardiography or ECG). Its extended recording period is sometimes useful for observing occasional cardiac arrhythmias which would be difficult to identify in a shorter period. For patients having more transient symptoms, a cardiac event monitor which can be worn for a ...
