SVT Symptoms: What They Are, Why They Happen, and What to Do

When your heart suddenly races for no clear reason—like it’s trying to escape your chest—you might be experiencing supraventricular tachycardia, a type of abnormal heart rhythm that starts above the heart’s lower chambers. Also known as SVT, it’s not always dangerous, but it can feel terrifying. Many people mistake it for a panic attack, but SVT is a real electrical glitch in the heart’s wiring, not just stress. You don’t need to be old or unhealthy to get it. It can hit someone in their 20s during a workout, while sitting at a desk, or even after drinking too much coffee.

Common SVT symptoms, include a pounding heartbeat that comes on fast and lasts from seconds to hours, dizziness, shortness of breath, chest pressure, and sometimes fainting. Some people feel like their heart is fluttering or skipping, while others just feel exhausted for no reason. These episodes often start and stop suddenly, which is why many ignore them—until they happen again, or worse, in public. If you’ve had one episode, you’re more likely to have another. Triggers? Caffeine, alcohol, stress, dehydration, or even hormonal changes. For some, it’s nothing more than an annoyance. For others, it’s a sign something deeper needs checking.

It’s not just about the heartbeat. SVT can affect your whole day. You might avoid exercise because you fear an episode. You might stop drinking coffee, skip social events, or feel anxious waiting for the next one. That’s why understanding your symptoms matters—not just to treat the heart, but to reclaim your life. The good news? Many cases are manageable with simple lifestyle tweaks, breathing techniques, or medication. You don’t have to live in fear of your own pulse.
