If the symptoms persist, get thyroid function test

stay hydrated, meditate if possible. reduce caffeine intake, avoid intake in evening and late in night.

1. This ECG is reassuring — you do not need to panic or rush to emergency based on this report. 2. Still see a cardiologist / physician within 1–2 weeks (not emergency) because: • You have ongoing palpitations + anxiety • One normal ECG does not rule out intermittent arrhythmias (e.g., PVCs, SVT, inappropriate sinus tachycardia) • Recommended tests to completely reassure you: • 24–48 hour Holter monitor (captures heart rhythm during daily life + during palpitations) • 2D Echocardiography (checks heart structure/valves/function — very useful for anxiety) • Thyroid function (TSH + free T4) — hyperthyroidism can cause palpitations • Electrolytes (K, Mg, Ca) — low levels can trigger palpitations 3. Go to ER / hospital same day only if: • Palpitations become very fast (>150 bpm) and sustained • Chest pain with palpitations • Dizziness → near-fainting • Shortness of breath or severe weakness

• For anxiety & palpitations right now (safe to try): • Practice 4-7-8 breathing (inhale 4 sec, hold 7 sec, exhale 8 sec) × 5 cycles when palpitations start — works very well for most people • Avoid caffeine, energy drinks, strong tea after 2 pm • Sleep 7–8 hours, fixed timing • Limit screen time 1 hour before bed • Gentle walk 20–30 min daily — helps regulate heart rate • Do not keep doing repeated ECGs on your own — it increases anxiety and rarely adds new information if previous ones are normal. • Keep a simple diary: time of palpitations, duration, what you were doing/feeling — very helpful for doctor/Holter correlation. Your heart is most likely perfectly normal — the symptoms are almost certainly from anxiety + heightened awareness (very common in young adults who check ECGs repeatedly). A Holter monitor + echo will give you 99% peace of mind. Please see a cardiologist soon (show this ECG + your symptoms) — once they confirm normal, the worry usually drops dramatically. If you want help preparing questions for the doctor or if palpitations change (frequency, duration), feel free to consult online. Take care — stay calm, you are okay
