- Get it checked out. I have a similar problem. After 6 sedentary
- years (I ran XC, rowed crew in U.) I took up running again: 30 mins/day,
- 6 days a week, at a target HR of 156. Soon I had a chronic arrhythmia,
- a skipped beat every fourth beat. (At the time my morning rising pulse
- was 68). A quick-'n'-dirty EKG revealed a lot of PAC's (premature
- atrial contractions), but also what looked like PVC's (p. ventricular
- c.'s), which are much more serious.
- Had an echocardiogram, treadmill stress test, and a 24-hour Holter
- monitor done. Echo showed mild MVP (mitral valve prolapse), a common
- condition in tall skinny folks with pectus excavatus (hollow chests!).
- Especially common with athletes' large, floppy hearts. The PVC's turned
- out, on very close examination of the Holter monitor record, to be all
- PAC's with associated right bundle branch block, again a common syndrome
- with endurance athletes.
- BTW, at high heart rates all pulse irregularities disappeared!
- I knocked off training entirely, drank beer for 2 weeks, and started
- over, running only 20 mins. every other day. Every 4 weeks I added 5
- minutes to the total time. I'm up to 60 mins. every other day. Morning
- rising HR is now 50 (my all-time low was 36, rowing crew), and skipped
- beats are a rarity, usually occurring only in the couple of hours after
- a run.
- So I turned out OK. But you may not have the same problem. I
- encourage you to get tested, pronto monto. PVC's are potentially
- serious bidness.
