2. Multifocal atrial tachycardia - Wikipedia

   en.wikipedia.org/wiki/Multifocal_atrial_tachycardia

   Multifocal atrial tachycardia is characterized by an electrocardiogram (ECG) strip with three or more discrete P wave morphologies in the same lead, not including that originating from the sinoatrial node, plus tachycardia, which is a heart rate exceeding 100 beats per minute (although some suggest using a threshold of 90 beats per minute ...

4. Rhythm interpretation - Wikipedia

   en.wikipedia.org/wiki/Rhythm_interpretation

   There are 6 different sinus arrhythmia. [1] [2]A normal heart should have a normal sinus rhythm, this rhythm can be identified by a ventricular rate of 60-100 bpm, at a regular rate, with a normal PR interval (0.12 to 0.20 second) and a normal QRS complex (0.12 second and less).

5. PR interval - Wikipedia

   en.wikipedia.org/wiki/PR_interval

   Schematic representation of a normal sinus rhythm EKG wave. In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration.

6. Electrocardiography - Wikipedia

   en.wikipedia.org/wiki/Electrocardiography

   Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.

9. Cardiac stress test - Wikipedia

   en.wikipedia.org/wiki/Cardiac_stress_test

   A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
