ECG compentency

Sinus Rythmn

• Regular HR

• P wave- for every QRS

• PR: 0.12-2 QRS: 0.06-1

• Treatment: continue to monitor

Sinus Tachy

• 100-160 HR

• Regular

• Pwave for every QRS

• PR and QRS normal range

• Treatment: Adenosine 6mg, BB (metroprolol) , catheter Ablation, vageul manuvers

Sinus Bradycardia

• <60 HR

• regular

• p wave for every QRS

• PR interval and QRS normal

• Treatment: 1. treat the underlying cuase if symptomatic , Atropine 0.5mg then 1mg every 3-5 mins, if atropine does work pacing

PVC- Premature Ventricular Contraction

• not correlated with a specific heart rate

• Early irregular beats

• Pwave absent

• PR interval unmeasurable

• QRS greater than 0.12 sec

• Treatment: not generally treated unless symptomatic: BB, antiarrhythmic meds, amiodarone 6mg

A fib

• Ventricalur 60-100 atrial >300

• irregular

• no p wave

• PR unmeasurable

• QRS in range

• Treatment: control heart rate and rythm, BB/CCB, Amiodarone 6mg, anticoagulants: wafrain, heparin,

A flutter

• ventriacal 60-100 atrial 250-400

• irregular

• P wave are sawtooth flutter waves

• PR unmeasurable

• QRS in range

• Treament: Antiarrhythmics and anticoagulants, prepare for cardioversion

SVT- Supraventricular tachycardia

• 150-250

• Regular

• P waves are present but often hidden within QRS complex

• PR unmeasurable

• QRS in range

• Treatment: vagal maneuvers, Adenosine 6mg IV over 1-3 sec then flush 20ML NS, IV CCB/BB

QT range

0.36-.044
