  1. PVC’s • darren peress md fhrs • Tucson Medical Center Cardiac symposium

  2. PREMATURE VENTRICULAR CONTRACTIONS (PVC’S) VENTRICULAR PREMATURE BEATS (VPB’S) VENTRICULAR ECTOPIC BEAT’S

  3. TEXT

  4. SYMPTOMS SKIPPED BEATS EXTRA BEATS MISSING BEATS THUMPING FORCEFUL BEATS CHEST +/- THROAT CHEST PAIN DIZZINESS EFFECTIVE BRADYCARDIA RACING

  5. HOW COMMON MULTIPLE RISK FACTOR INTERVENTION TRIAL (MR FIT) PVC’S ON A TWO MINUTE RHYTHM STRIP ... 4.4% OF APPARENTLY HEALTHY WHITE MEN 24 H HOLTER MONITORING OF MALE MEDICAL STUDENTS ... 50 % HAD AT LEAST ONE PVC, 2 % HAD MORE THAN 50. BY EXERCISE STRESS TESTING ... 7 - 20 %

  6. STATISTICAL IMPLICATIONS IN MR FIT 3 FOLD INCREASE IN SCD AT 7 YR FOLLOW UP IN A STUDY OF 45K VETERANS 3.8 % HAD PVC’S ON A RESTING EKG AND A SIGNIFICANTLY HIGHER MORTALITY (39 VS 22 %) SIMILAR FINDINGS ELSEWHERE

  7. HOW USEFUL IS THIS... NOT PARTICULARLY... POPULATION BASED BUT WE’RE DEALING WITH INDIVIDUALS

  8. HOW DO PEOPLE PRACTICE

  9. ELECTROPHYSIOLOGISTS PRACTICE WITH THE FOLLOWING PRINCIPLES

  10. ELECTROPHYSIOLOGISTS PRACTICE WITH THE FOLLOWING PRINCIPLES 1. EXCLUDE STRUCTURAL HEART DISEASE (LV DYSFUNCTION ETC)

  11. ELECTROPHYSIOLOGISTS PRACTICE WITH THE FOLLOWING PRINCIPLES 1. EXCLUDE STRUCTURAL HEART DISEASE (LV DYSFUNCTION ETC) 2. EXCLUDE CAD AND LOOK FOR VT WITH EXERCISE

  12. ELECTROPHYSIOLOGISTS PRACTICE WITH THE FOLLOWING PRINCIPLES 1. EXCLUDE STRUCTURAL HEART DISEASE (LV DYSFUNCTION ETC) 2. EXCLUDE CAD AND LOOK FOR VT WITH EXERCISE 3. IS IT A TYPICAL BENIGN PVC? (REALIZING THAT A SMALL PROPORTION OF THESE ARE LIFE THREATENING)

  13. ELECTROPHYSIOLOGISTS PRACTICE WITH THE FOLLOWING PRINCIPLES 1. EXCLUDE STRUCTURAL HEART DISEASE (LV DYSFUNCTION ETC) 2. EXCLUDE CAD AND LOOK FOR VT WITH EXERCISE 3. IS IT A TYPICAL BENIGN PVC? (REALIZING THAT A SMALL PROPORTION OF THESE ARE LIFE THREATENING) 4. IS THERE ANYTHINNG ELSE OBVIOUSLY WRONG ( QT PROLONGATION ETC...)

  14. WHO IS AT RISK? LV DYSFUNCTION CAD CMP QT PROLONGATION SYNCOPE SHORT COUPLED/FAST NSVT HIGH PVC BURDEN FHX SCD

  15. ONCE YOU’VE ASSESSED RISK, ASSESS SYMPTOMS

  16. CASE ONE 23 YEAR OLD WOMAN WITH INCIDENTALLY DISCOVERED PVC’S. NO SYMPTOMS. OTHERWISE NORMAL EKG.

  17. AVAILABLE TESTS EKG EXERCISE STRESS TEST HOLTER ECHO MRI

  18. CASE TWO 23 YEAR OLD WOMAN WITH PALPITATIONS DUE TO UNIFOCAL PVC’S. MODERATELY BOTHERSOME.

  19. HER HISTORY.... SKIPPED BEATS NO RACING NO SYNCOPE NO FAMILY HX SCD NORMAL EKG RVOT MORPHOLOGY PVC’S NO VT NORMAL ECHO AT REST/MORE SO WITH ACTIVITY 3 CUPS OF COFFEE A DAY NO MEDS

  20. COFFEE OVERRATED

  21. ADENOSINE FOR SUSTAINED VT BETA BLOCKERS EFFECTIVE IN 25 - 50 % CALCIUM CHANNEL BLOCKERS EFFECTIVE 25 - 30 % COMBINATION OF BB AND CACB SYNERGISTIC DILT AND VERAPAMIL EQUALLY EFFECTIVE 1C RX EFFECTIVE 25 - 50 % SOTALOL AND AMIO MORE EFFECTIVE

  22. ABLATION

  23. CLOSELY RELATED 41 YO WITH NEAR SYNCOPE AND MMVT.....

  24. CASE THREE 72 YO MAN WITH NO PALPITATIONS BUT A 20 Y H/O PVC’S. 25 K PVC’S A DAY. EF 35 %. FAILED BB AND AA DRUGS. FAILED 8 HOUR ABLATION IN CHICAGO.
