The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Mirtazepine does have a strong antihistaminic and some anticholinergic effects. Fluvoxamine ; venlafaxine are reportedly devoid of these effects. ...Read more
R-r interval: An ECG has various titled waves. The r wave is part of ventricular depolarization. The r to r interval is the time between ventricular depolarizations. This is usually transposable to heart rate. The holter is a 24 hour ECG recording. An r-r interval of 1second equates to a heart rate of 60 beats per minute. ...Read more
