Recovery PVCs ....

My questions are related to a study about recovery PVC's that has been published in 2008 (and i also seen Dr. George D. Lundberg for teh same) and apart of the study is as says (Whereas exercise PVCs were related to the heart rate increase with exercise, recovery PVCs were related to coronary disease (previous myocardial infarction, coronary revascularization procedure, or pathological Q waves on resting electrocardiogram# and ST-segment depression).  My Questions:

1- What is the meaning of heart failure–free patients in this study.
2- what is the meaning of (related to) in the statement above? are those subjects who underwent clinical treadmill testing in this study have pervious heart problems or they are normal people with no heart structure problems? Thx"

Honestly, I have no idea because I've never read up on the subject. I've just heard comments on post exercise PVC increase being bad.

I had a stress test done, made it through but my heart was kicking out PVC's like crazy afterwards during the recovery period. The two women (nurses? techs?) mentioned it. Of course I could feel my heart doing the jitterbug in there but I just laughed and told them that was normal for my heart (it is). I never heard any more about the test results. I guess I'm going to live. I don't have heart "disease" but I've had a lifetime of arrythmias and a heart murmur.

can you list the 2008 study you're referring to? I believe it may be the same one that someone else asked about back in Sept 2010 in the heart disease forum.

arrhythmia's and exercise/recovery is something I've asked tons of questions about both here and to my doctor's - there is so much controversy over pvc's themselves when you add in the mix exercise/recovery you may get 10 different answers such as I have.

Dr. Lundberg's medscape video & article were discussed here in the HR forum; lots of interesting info; I'll see if I can find the previous thread also that discusses it.  Here's his original medscape video: http://www.medscape.com/viewarticle/571891 which he does refer to Dewey's research the first article you quoted.

Here's one thread: http://www.medhelp.org/posts/Heart-Rhythm/recovery-pvcs/show/1523943  ;

I believe they are referring to things like coronary heart disease, cardiomyopathy, valvular heart diseases.  Age seems to play a big part in most of these studies, because as we age there seems to be a higher propensity for many health related issues.

Here's a post I did recently http://www.medhelp.org/posts/Heart-Rhythm/Exercise-and-arrhythmias/show/1528523  with more info about exercise and arrhythmia's.

The below points are part of the study..... its clear that the study was done on old subjects with perviuos CD and heart problems. So can we apply this on adults with normal heart structure and recovery PVC.s.... ??? any feedback is helpful.

http://www.medscape.org/viewarticle/569721

•Greater age, greater height, higher systolic blood pressure, higher resting heart rate, greater corrected QT interval, PVCs at rest, and greater increase in heart rate with exercise were associated with greater odds of frequent exercise PVCs (P < .05).
•Subjects who were older and taller and who had greater systolic blood pressure, previous coronary disease, PVCs at test, abnormal ST-segment depression, and exercise PVCs had greater odds of both infrequent and frequent recovery PVCs (P < .05).
•Resting PVCs, age, and systolic blood pressure were key predictors of both exercise and recovery PVCs.
•Whereas exercise PVCs were related to the heart rate increase with exercise, recovery PVCs were related to coronary disease (previous myocardial infarction, coronary revascularization procedure, or pathologic Q waves on resting electrocardiogram) and ST-segment depression.

I don't think so, someone will correct me if I'm wrong but I don't think we can compare young healthy individuals with older males with previous CD and heart problems.

One key point I've said before I have questions about is this "a lack of cool-down walk that may have led to a difference in prevalence and significance of recovery PVCs" I'm not sure what part that plays in the actual numbers they're using for the study.

Some things we can learn from these studies though are to exercise, eat well, maintain a healthy bp and reduce stress so as we age we stay healthy...much easier said than done.

Also this study does talk about Frequent ectopy >greater than 7 PVCs per minute (10,080 24/hrs) is associated with adverse prognosis in some populations, but doesn't go into details about what the parameters are for those populations.

I see some exclusion criteria; but they didn't say whether the men exercised before or if they had high fat diets, whether they smoked, drank coffee or many other things that may make the study seem a bit on the higher side for pvc's.

I wish I could find an across the board study on individuals from all ages.
