Atrial Tachycardia is another Supraventricular Tachycardia. Atrial tachycardia is usually caused by an abnormal conduction of electical impulses fromt he atria to the ventricles via an accessory pathway. This pathway usually occurs through the AV node, and causes a premature ventricular contraction.
Atrial Tachycardia ECG
Heart Rate: ussually greater than 160
Rhythm: essentially regular
Pacemaker Site: an ectopic atrial pacemaker site.
P-waves: present and normal.
PR Interval: Norrow – 0.08-0.12 seconds in duration.
QRS Complex: Normal or slightly longer than normal in duration (greater than .10 seconds).
Atrial Tachycardia Signs and Symptoms
People who are in atrial tachycardia usually have the following signs and symptoms:
1. Signs associated with poor peripheral perfusion, such as pale, cold and clammy skin.
2. Complains of dizziness, anxiety, sense of impending doom, chest pain, chest tightness, nausea, and palpitations.
