Cardiac Dysrhythmias: Supraventricular tachycardia
Supraventricular tachycardia is increase in heart rate over 150 bpm due to do the over firing or redirected firing of the SA Node conduction above the ventricles. With supraventricular tachycardia the patient can have an abrupt onset and termination of rhythm, flattened or retrograde conduction P waves and narrow QRS waves specifically less than 0.08 second (Kyle, 2012).
Clinical Manifestations and Pathophysiology The clinical manifestations of supraventricular tachycardia are palpitations, dizziness, light-headedness, or fainting, shortness of breath, anxiety, chest pain and/or tightness. Some patients might not show any clinical manifestations and just feel show some discomfort (Hinkle, 2014).With pathophysiology of the supraventricular tachycardia the SA node may be firing to quickly causing the rapid heart rate or the SA node may be firing but it diverts its normal pathway due to an extra electrical pathway which is called Wolff-Parkinson-White (Wang, 2016).Due to the rapid heart rate the heart itself cannot fully contract which leads to less oxygen to the lungs and brain which then results in shortness of breath and anxiety. If rapid heart rate does not decrease that can lead to heart failure and death. Nursing Management With…
