A normal coronary CT scan shows that your large heart arteries are likely clear, but palpitations and dizziness can still arise from other heart or non-heart causes. Conditions like arrhythmias (irregular heartbeats), problems with heart's electrical system, or even low blood pressure can cause these symptoms despite a normal CT scan.

⚕️ What This Likely Means

Your symptoms may be related to functional or electrical heart issues not visible on a coronary CT scan, such as atrial fibrillation or other arrhythmias. Non-cardiac causes like dehydration, anemia, or inner ear problems can also cause dizziness and palpitations.

⚠️ When to Seek Immediate Care

• If palpitations are accompanied by chest pain, severe shortness of breath, or fainting.
• If dizziness leads to falls or prolonged confusion.
• If symptoms worsen or become frequent.

🩺 Next Steps

• A detailed evaluation by a cardiologist is important; they may recommend an ECG (electrocardiogram), Holter monitor, or echocardiogram.
• Blood tests to check for anemia or thyroid issues might be helpful.
• Avoid stimulants like caffeine and ensure adequate hydration.

Please consult a cardiologist for thorough assessment and tailored management to address your symptoms safely.
