About the Blog

DrJohnM is a medical blog that I began in 2009, for no apparent reason. It commenced on a whim without any grand plan. Then, one thing led to another, and I was hooked.

I love being a learner. For me, learning stuff is cool, not just because of the facts or figures that make you feel smarter, but mostly because the journey of discovery feels as rewarding as a great mountain bike ride on a new trail. Discovering something new makes me think, “Man, I can’t wait to tell my buds about that.”

I write about electrophysiology, cardiology, health, doctoring and endurance sports.

We all know that the internet overflows with information on topics that I write about, like AF for instance. My goal, therefore, is not to replicate an encyclopedia, but to provide an inside-the-ropes look at things that I know and live.

The goals of DrJohnM:

  • To educate on the science of heart rhythm and general cardiac matters.
  • To emphasize the importance of healthy living choices for preventing heart disease—the most preventable disease.
  • To share a raft with you down the roaring river that is the world of doctoring.
  • To mesh the world of cycling (endurance sports) and medicine.


  1. Patient information is sufficiently changed and kept generic enough to protect the privacy of patients.
  2. My writings should not be construed as medical advice.  Discuss your treatment strategies with your doctor.
  3. My opinions are my own, and are based on personal experiences. I will reference sources when applicable. Please do not confuse a blog post with a scientific paper or multi-referenced review article. I don’t have an army of foundation-supported researchers. It’s just me trying to help.
  4. If I am wrong about something, by all means point out my mistake. Bike-racing cardiologists have thick skin. Conversation makes a blog much better.
  5. I’m not a professional writer; obviously you have seen this. I promise to keep trying to improve at the craft. I wished that I paid more attention to the rules of writing as a younger.
  6. WordPress requires your email to comment.  Your email address is kept confidential and will not ever be published.

Enjoy. Interact. School me.
