Question

A--- &causes:Distortion of an ECG tracing by electrical activity that is noncardiac in origin

Can mimic various cardiac dysrhythmias, including ventricular fibrillation
Patient evaluation essential before initiating any medical intervention
Loose electrodes
Broken ECG cables or broken wires
Muscle tremor
Patient movement
External chest compressions
60-cycle interference

Answer 1

ECG abnormalities can be caused by noncardiac electrical activity, leading to distortions in the ECG tracing. Common causes include loose electrodes, broken cables or wires, muscle tremors, patient movement, chest compressions, and electrical interference. These distortions can mimic various cardiac dysrhythmias, requiring careful evaluation before initiating medical intervention.

Step-by-step explanation:

ECG Abnormalities

ECG abnormalities can be caused by various factors including electrical activity noncardiac in origin. These noncardiac factors can distort an ECG tracing and mimic different cardiac dysrhythmias. It is important to evaluate the patient before initiating any medical intervention to ensure accurate diagnosis and appropriate treatment.

Possible Causes of ECG Distortion

• Loose electrodes
• Broken ECG cables or wires
• Muscle tremor
• Patient movement during the ECG recording
• External chest compressions
• Interference from 60-cycle electrical activity

Common ECG Abnormalities

Some common ECG abnormalities include:

1. Second-degree or partial block
2. Atrial fibrillation
3. Ventricular tachycardia
4. Ventricular fibrillation
5. Third-degree block
