N211: Health Differences Across the Lifespan I

Correct the underlying cause Correct hypoxia, heart failure or imbalance. PSVT 2ND DEGREE HEART BLOCK #1


AV ischemia secondary to occlusion of R coronary artery. Atrial rate is higher than Ventricle rate Atrial is regular – Ventricle is irregular PR continues to lengthen until a QRS is periodically dropped. Asymptomatic Decrease in BP, SOB, CHF, Chest pain, decrease LOC

Paroxysmal supraventricular tachycardia Includes all tachycardic dysrhythmias. Starts & stops suddenly Narrow QRS Ectopic Focus below the SA and above the AV 150-250bpm Decrease BP CAN’T SUSTAIN LIFE FOR LONG a block between the atria & ventricle P is upright PR = .20sec < QRS = .10> Asymptomatic Monitor closely Ischemia, AV injury, meds, rheumatic heart, Hyperkalemia, MI, increased vagal tone 1ST DEGREE HEART BLOCK

From a L coronary artery occlusion & MI. & Myocarditis


Atrial rate is greater than ventricle rate Can progress to complete block rapidly without warning.

Signs & Symptoms (S/S)

EKG Atropine Pacing


Diagnosis (Dx)

3rd DEGREE HEART BLOCK COMPLETE HEART BLOCK Complete block. Atria 7 Ventricle is independent of each other


P wave is WNL NO PR interval QRS narrow or wide

Signs & Symptoms (S/S)

MI, often resolves on its own within 1 week.
