EKG Interpretation - TMC Exam Questions With 100% Verified Solutions.

normal characteristics 12 lead ecg - correct answer -AVR & V1 leads show predominantly negative QRS complex -T-wave upright in leads I & II -R-wave V1 will be small and increase in each chest lead as you approach V5. ischemia - correct answer reduced blood flow - inverted T wave injury - correct answer acute tissue damage - change in ST segment infarction - correct answer necrosis/tissue death - significant Q waves sinus arrythmia treatment - correct answer treat other symptoms sinus tachycardia - correct answer oxygen sinus bradycardia - correct answer oxygen, atropine atrial flutter - correct answer digoxin, beta blockers, calcium channel blockers atrial fibrilation - correct answer digoxin, beta blockers, calcium channel blockers, anticoagulants, antithrombolitics PVC - correct answer oxygen, lidocaine, treat other causes pulseless ventricular tachycardia - correct answer CPR, defibrillation, epinephrine, amiodarone ventricular tachycardia with pulse - correct answer cardiovert Ventricular fibrillation - correct answer defibrillate, CPR, epinephrine, amiodarone asystole - correct answer confirm in 2 leads first, CPR, epinephrine Sinus bradycardia (ECG) - correct answer positive P wave Rate < 60 Atrial Flutter (ECG) - correct answer P waves "sawtooth" appearance Atrial Fibrillation (ECG) - correct answer no visible p waves, irregular baseline QRS also irregular PVC (ECG) - correct answer side to side - ventricular Multifocal PVC (ECG) - correct answer up down & side to side - ECG is all over the place occurs in different parts of the ventricle Sinus Tachycardia (ECG) - correct answer positive P wave rate > 100 Arrythmia (ECG) - correct answer positive P wave, irregular rate Ventricular flutter/fibrilation (ECG) - correct answer completely irregular ventricular rhythm Ventricular tachycardia (ECG) - correct answer ventricular rhythm with rate > 100 (this is an emergency!)
