What is a cardiac dysrhythmia?
A cardiac dysrhythmia (also called arrhythmia) is an abnormal or irregular heartbeat. An abnormal heart rate means that your heart rate is either too fast (typically over 100 beats per minute) or too slow (typically below 60 beats per minute). On the other hand, an irregular heartbeat means that your heart’s rhythm is disrupted in some way.

What causes a dysrhythmia?
Usually, some sort of trigger disrupts the heart’s rate or rhythm, leading to a dysrhythmia. The most common triggers include: Damage to your heart from a heart condition like coronary artery disease or cardiomyopathy. Problems with your heart’s conduction system. Electrolyte, hormone or fluid imbalances in your blood.

How do you know if you have a dysrhythmia?
A dysrhythmia may be “silent” and not cause any symptoms. Your healthcare provider can detect an irregular heartbeat during an exam by taking your pulse, listening to your heart or running diagnostic tests. If symptoms occur, they may include: Palpitations: A feeling of skipped heartbeats, fluttering, “flip-flops” or your heart “running away.”

Jan 21, 2024 · Arrhythmia or dysrhythmia are disturbances in the normal cardiac rhythm of the heart which occur as a result of alterations within the conduction of electrical impulses. These impulses stimulate and coordinate atrial and ventricular myocardial contractions that provide cardiac output.

- Rhythm. Assess ventricular (RR intervals) and atrial (PP intervals) rate and rhythm: Is ventricular rhythm regular? What is the ventricular rate (beats/min)?
- P-wave morphology and PR interval. Assess P-wave morphology and PR interval. P-wave is always positive in lead II (actually always positive in leads II, III and aVF).
- QRS complex. Assess QRS duration, amplitudes, Q-waves, R-wave progression and axis. QRS duration must be <0,12 s (normally 0,07-0,10 s). There must be at least one limb lead with R-wave amplitude >5 mm and at least one chest (precordial) lead with R-wave amplitude >10 mm; otherwise, there is low voltage.
- ST segment. Assess the ST segment (morphology, depression, elevation) The ST segment should be flat and isoelectric (at level with the baseline). It may be slightly upsloping at the transition with the T-wave.

When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes. For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75). The second method can be used with an irregular rhythm to estimate the rate.

Oct 13, 2023 · Tests. Tests to diagnose a heart arrhythmia may include: Electrocardiogram (ECG or EKG). This quick test measures the electrical activity of the heart. It can show how fast or how slow the heart is beating. Sticky patches called sensors are attached to the chest and sometimes to the arms or legs. Wires connect the patches to a computer, which ...
