Normal, Skipped, or Irregular Heart Beats

Your heart can get out of rhythm. Dr. Gregory Marcus explores why the heart may beat too slowly or too fast, or in a disorganized or chaotic manner. Some of these different types of arrhythmias can be dangerous if not properly treated, while others may be annoying but are not life-threatening. Find out how to tell the difference.

Everyone that worries about ectopics and palpitations should watch this to get a better understanding about the heart rather than watching endless videos by anxiety coaches and tormenting themselves with what ifs and procrastination. No.1, visit your GP, get a second opinion or even a third. No.2, get stress test and echocardiogram. If all is okay then No.3, get on with your life. Keep off the internet. If you can spend hours watching anxiety videos you can spend hours exercising, eating well and relaxing!

I fainted for the first time in my life and after a few months have finally been given an all-clear. I learned a lot of this material and this is very well explained in one presentation.

[shkelzennokaj]

Your Grandfather's story about living with PVC almost 100 years old, is probably going to help us more than everything you said so far. Great information, especially when we know its coming from a proven authority rather than just some youtubers clickbaiting us for some views.

I’ve had an AFIB issue for almost 9 years. I had two ablations about 5 years ago and was fine until about 2 weeks ago. I’m currently tryin a new medication instead of another ablation. (So far)
I learned more about my condition from this video than I learned in 9 years. And the information GREATLY reduced my stress level.
Thank you Dr. Marcus. Very well done.
I also watched the video specific to AFIB. Very good too. But this explained my occasional missed beats.

In Jan 2011 I had a PE-induced heart attack after prostate/bladder surgery. I was diagnosed to having idiopathic multi-factor (II and VIII) thrombophilia. I've had afib ever since. I've been on the Coumadin-for-life program, too. I have a home meter, test weekly and adjust my dosage to stay at a target of 2.5. I bridge with injectable Lovenox for invasive procedures.

In the past eleven, years I've seen 7 different cardiologists and just learned more from you in an hour that I did from all seven in eleven years.

By the way, I'm now 75 with stage 3 polyosteoarthritis and because of the Coumadin, can't take anti-imflammatory meds. I'm also highly intolerant of narcotics.

I think it's time to see a hematologist to change from Coumadin.

Thank you so much for taking the time to make this video.

Really loved Dr. Marcus’s presentation. It was so very informative, and delivered graciously. 🙏👏🏻

[ahlamkamil]

Wonderful indeed.
I have permanent AFib and suffered so much for years . So many medications were tried. At the beginning, they tried to control the rythme which did not help. Controlling the rate worked better, though after trying a number of medications with doses that went up and down. Now l feel more stable with diltiazim and bisoprolol plus taking 10 mg of Eliquis in two doses.
Thank you for this great lecture

This is an excellent video on the heart. I've watched many videos on the heart and this is the best one I've seen. It's very easy to understand. It's also very informative and extremely helpful. Thank you very much for posting this.

[PianoMatronNeeNee]

Very informative. You are a natural teacher. A million thanks yous from Miami.

[rajrai]

Excellent presentation doctor 👍🏻 Similarly could you please make one about Branch Blocks, because I was diagnosed with RBBB two years ago, but doc said it was not too much of a thing to worry about, but I could still get properly assessed if I was worried. Since I was going to travel a lot very soon I decided not to follow through right then, and so would be very grateful for your help.

[ivanhoe]

Fantastic information that has made me feel so much better. Thank-you.

[Bridgeoverthevalley]

I am 79 y o man & currently wearing a mini monitor because of being notified of Afib App on Apple Watch. My MD thinks false + but wants to be sure. Thank you for this enlightening presentation.

[tooneboone]

Great info. I am having 15 to 20 skipped beats a minute and am having trouble getting a satisfactory diagnosis. I have a kardia mobile and have shared the history with my (electro) Doctor. I am also a white male of 84 yrs. old and have had an Aortic valve replaced in 2013. I am not overly concerned.

[twintwitch]

Awesome discussion and explanations. Very understandable even for a lay person

[mjg]

Very useful. Thank you for this valuable presentation.
