SVT Maybe
theinzanas posted:
So I recently had a epsidoe of heart palpitation (flutter in upper chest and throat), near fainting followed by wicked headache. Last time this hhappened rushed to the ER to be told that everything was fine and to follow up with Cardio. Followed with Cardio, he stated it might be SVT I wore a halter monitor, had a nuclear stress test and they found nothing. Well just about an hour ago had the exact same episode. Flutter, followed by near fainting, dizziness, fatigue and wicked headache and slight shortness of breath. Wondering if all these test came back negative could I still have SVT?

It's possible.

"He stated it might be SVT. I wore a Holter monitor"

Noteworthy, to use for a much longer period of time, an event recorder, or at the very extreme, a insertable cardiac monitor (ICM) , can often capture/record an elusive heart rhythm disturbance/problem, be it a fast, slow or irregular pattern.

As applicable to the patient, paroxsymal supraventricular tachycardia (PSVT) typically causes a frightening burst/surge in heart/pulse rate that begins/starts and ends/stops suddenly (hence the term paroxsymal), which can last for just mere seconds or it can continue on for minutes to hours to days. SVT can send the heart into speeds up to 150-200 BPM, and sometimes, even as high as 300 BPM.

Symptoms that may/can occur with SVT, PSVT, as well as PVCs (typically premature ventricular contractions, palpitations), includes chest pain/discomfort/pressure/tightness, shortness of breath, lightheadedness/dizziness, and in uncommon to rare cases, syncope (temporary loss of consciousness, which includes passing out or fainting, includes near-fainting too). Sometimes there are no symptoms.

Additionally, of the various types/kinds of heart conditions, symptoms may/can be acute (occurring suddenly), be chronic (occurring over a long period of time), come and go (be transient, fleeting or episodic) or even be silent.

Best of luck down the road of life.

Calming the HEART

Techniques at Home (as 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.



Be a questioning patient. TALK to your DOCTOR and ASK QUESTIONS. Studies show that patients who ask the most questions, and are most assertive, get the best results. Be vigilant and speak up!"
