Palpitations and panic attacks are often considered as arrhythmias.
Arrhythmia is mainly manifested as abnormal rhythm and frequency of the heart, and the common clinical arrhythmias can be categorized into pre-systole, ectopic tachycardia, atrial flutter and atrial fibrillation, and atrioventricular (AV) block.
1. Pre-periodic contraction is the most common arrhythmia in clinic, which is the electrical-mechanical activity of the heart caused by the impulses sent out in advance from the ectopic pacing point other than the sinus node, with occasional palpitations, panic, chest tightness, shortness of breath, fatigue, and a short duration of the attack.
2. Ectopic tachycardia refers to the occurrence of 3 or more consecutive preterm contractions, which are often asymptomatic when the attack is short-lived, and the persistent attack may be characterized by chest pain, palpitation, dizziness, panic, fatigue and even syncope.
3. Atrial flutter and atrial fibrillation are more serious, patients often have palpitations, chest tightness, dizziness, fatigue, etc., often accompanied by anxiety.
4. Patients with first-degree and second-degree atrioventricular block are asymptomatic or only have palpitations and a sense of heartbeat loss, while patients with third-degree atrioventricular block often have fatigue, weakness, dizziness and even syncope.
If you feel palpitations and panic, you should go to the hospital in time and follow the doctor’s instructions for treatment.
