Characteristics: early P’ wave; QRS width WNL
The drug presentations will be on Monday, February 25. Each group is assigned one drug classification. Within that classification, please choose a specific generic or name brand drug to review. Each presentation lasts 5-8 minutes. Create a one-page handout to distibute your teacher and classmates (19 copies). Presentation should be on transparencies. Font should be at least 18-point. Here are the groups:
1. Cardioplosion (Arik, Michael, Greg) : Beta Blockers2. Pacers (Belinda, Jamie, Sean) : Diuretics
3. Valentines (Linda, Katie, Chenell) : Calcium Channel Blockers (CCBs)
4. Kidney Savers (Deena, Stacie, Heng Ju): Angiotensin Converting Enzyme (ACE) Inhibitors
5. Team Stroke (Eric, Alan, Liz) : Cardiac Glycosides (Digitalis)
6. The Dissociators (Doug, Becky, Chad) : Nitrates/Nitroglycerine
Premature atrial contraction (PAC)
A premature beat conducted from an irritable atrial focus.Characteristics: early P’ wave; QRS width WNL
Premature ventricular contraction (PVC)
A premature beat conducted from an ectopic ventricular focus.Characteristics: early; no P; QRS BIG & WIDE! Compensatory pause.
Ventricular bigeminy
A pattern w/ a premature beat following a normally-conducted beat (premature-normal-premature-normal)
Trigeminy:
A pattern w/ a premature beat following two normally-conducted beat (premature-normal-normal-premature-normal-normal)
PVCs can present in ‘couplets’.
The image shows couplets with 'R on T' phenomenon.
Atrial (supraventricular) tachycardia (PAT)
AKA Paroxysmal Atrial Tachycardia -- Bursts of high rate rhythm originating from irritable atrial focus
May also have PJT (no P or ‘retrograde’ P). See Dubin for examples.
Ventricular tachycardia (V Tach)
Features: Bursts of high rate rhythm originating from an irritable ventricular focus. A run of 3 or > PVCs in a row.Paroxysmal or sustained (>30 sec)
Ventricular fibrillation (V. Fib)
Cardiac arrest! A dire emergency requiring immediate treatment. Defibrillation!
A Story Without a Happy Ending: Janice showed an EKG case study of an acute MI resulting in V-fib and death. CPR compressions are shown on the last frame. PRACTICE YOUR CPR, everyone. YOU could save a life:-)
A Story With a Happy Ending: Janice showed a case involving a young male with a defect in a gene responsible for encoding a cardiac potassium channel. He was very prone to tachyarrhythmia and had been given an implanted cardioverter/defibrillator. On this day, it saved his life!
We finished class with a 1-point quiz!
