In the present study, our first aim was to assess the capability of body surface potential mapping (BSPM) QRS area analysis for detection and quantification of pressure overload-induced LVH compared ...
At a glance, the tracing appears to show sinus rhythm with first-degree AV block and junctional bigeminy. However, careful observation of the V1 lead shows regularly occurring P waves (↓ in Figure 2) ...
Indications for cardiac-resynchronization therapy (CRT) in patients with heart failure include a prolonged QRS interval (≥120 msec), in addition to other functional criteria. Some patients with narrow ...
QRS duration (QRSd) is one of several measures of heart function recorded during a routine electrocardiogram (ECG). It is a composite of waves showing the length of time it takes for an electrical ...

Mastering QT interval measurement for safer hearts
The QT interval on an ECG is a vital marker of heart health, but measuring and interpreting it correctly can be tricky. Advances in formulas, regulatory guidance, and AI-powered tools are helping ...
Enlarge Source: Learn the Heart Which of the following does the above ECG represent? The ECG shows sinus tachycardia at about 110 beats per minute with a prolonged PR of 0.22 seconds: first-degree ...
We reviewed randomized controlled trials, review articles and clinical practice guidelines to present a practical approach to the diagnosis and management of SVTs (Box 1). We focus on the most common ...
