Question

Rate: bpm Rhythm: Regular or Irregular ". Regular or Irregular Identify this rhythm: Possible causes: Medical Treatment: inhibit the flow of extracellular Ca 2 ions across cell membranes of cardiac cells, vascular tissue. They relax arterial smooth muscle, depress the rate of sinus node pacemaker, slow AV conduction, decrease heart rate, produce negative inotropic effect. is a class of drugs used to prevent the extension and formation of clots by inhibiting factors in the clotting cascade and decreasing blood coagulability; used

Answer 1

7. Rate: 250 bpm. (1 large box = 300).

Rhythm: Regular ( R-R interval is uniform.)

Identify this rhythm: Ventricular tachycardia Monomorphic. Because the heart rate is fast. P wave is absent. QRS complex is wide.

Possible causes:

• Dilated cardiomyopathy
• Ischemic Heart disease
• Hypertrophic cardiomyopathy

Medical Treatment:

In a stable patient, VT monomorphic is treated with IV medication of amiodarone, procainamide to restore sinus rhythm. In an unstable patient, cardioverter-defibrillator implantation is necessary for the immediate recovery of the patient.
