13yr old w/ rapid heart rate
jlmlhc posted:
My 13yr old daughter had the flu 5 days ago that turned into dehyradation that took us to the ER for rapid heart rate (150 bpm) - EKG was fine except for the rapid rate - low potasium level - gave her IV and potasium supplement and sent her home - but her heart rate is still 100-120 at home and she is having a hard time sleeping ( I think shes worried) - took to her doctor and was advised to keep her drinking and eating but she is getting weaker. This happened 2 months ago and she was fine after 2 days but this is going on day 6. Doctor had me make appt with ped. cardiologist but can't get in until next week. Any advise?

Calming the HEART

Techniques at home (as deemed applicable to the patient)

Tighten stomach muscles. As soon as the heart starts to race, tighten the stomach muscles. This will cause the abdominal muscles to put pressure on a group of nerves that will tell the heart's electrical coduction system to slow down.

Chill. Take a deep, long breath and slowly let it out. Sometimes relaxation is all it takes to stop tachycardia. And deep breathing is frequently one of the fastest ways to relax.

Use common sense. Anything that speeds up the heart, caffeine and cigarettes, for example, can trigger a rapid heartbeat. So common sense says that if one is prone to tachycardia, one should avoid any substance that might give the heart an extra kick.

Best of luck to your daughter. May she live long and prosper.

Take care,

My husband and I both have SVT and I'm not sure if it is the same rapid heart rate as your daughter's, but try coughing and sometimes that stops it. Also, put your face in a very cold basin of water and put a bag of ice on your chest up near your neck. These have worked well for us. I talk a beta blocker and he is on varapidmill (sp???). Good luck. It's a scary feeling.
