[36F] Experiencing fainting, fatigue, and irregular heartbeat

What might be happening

Based on the information you have provided, possible diagnoses include:

• Supraventricular Tachycardia (SVT): Given your history of SVT, your symptoms of irregular heartbeats, lightheadedness, and fainting could be related to this condition. SVT is a condition where your heart suddenly beats much faster than it should. It usually happens because of faulty electrical connections in the heart.

  • Treatment options for SVT include medications, lifestyle changes, and sometimes procedures to correct the heart's electrical system.

• Orthostatic Hypotension: This condition causes a sudden drop in blood pressure when you stand up from a sitting or lying position, leading to lightheadedness and fainting. It could be a possibility given your symptoms, especially if these episodes occur when you stand up or start walking.

  • Treatment typically involves lifestyle modifications such as standing up slowly, staying hydrated, and avoiding alcohol and certain medications.

• Cardiac Arrhythmias: Given your history of SVT and your symptoms of irregular heartbeats and fainting, other types of cardiac arrhythmias could also be a possibility. These are conditions where the heart beats too fast, too slow, or irregularly.

  • Treatment depends on the type of arrhythmia and may include medications, lifestyle changes, and sometimes procedures or surgery.

• Neurocardiogenic Syncope (also known as Vasovagal Syncope): This is a common cause of fainting and can be triggered by various factors such as standing for long periods, heat exposure, or emotional distress. Given that your fainting episodes seem to occur when you're walking or upset, this could be a possibility.

  • Treatment typically involves lifestyle modifications such as staying hydrated and avoiding triggers.

What you can do

You should definitely seek medical attention for your symptoms. In the meantime, here are some things you can do:

1. Try to identify any triggers for your fainting episodes and avoid them if possible.
2. Stay hydrated and avoid alcohol, which can affect your heart rate and blood pressure.
3. Stand up slowly from a sitting or lying position to help prevent lightheadedness and fainting.
4. Continue taking your medications as prescribed.

What you should look out for

Seek immediate medical attention if you experience:

• Chest pain or discomfort
• Shortness of breath
• Severe or worsening symptoms
• Symptoms that interfere with your daily activities
