A cosa sono dovuti i battiti cardiaci bassi?
La bradicardia può essere causata da diversi fattori in grado di alterare i normali impulsi elettrici che controllano il battito del cuore: danni al tessuto muscolare del cuore (miocardio) legati all'invecchiamento. danni al tessuto cardiaco dovuti a un infarto del miocardio o altre malattie cardiovascolari.
What is bradycardia and what can cause it?
- In other cases, bradycardia can be a form of cardiac arrhythmia, a heart-rate abnormality. Cardiac arrhythmia can be caused by a problem in the sinus node, or it can be related to some disturbance in the passage of heartbeat signals through the A-V node and bundle of His.
How can you tell if you have bradycardia?
- Lightheadedness or dizziness (especially with exertion)
- Easy fatiguability
- Syncope (fainting) or near-syncope
- Dyspnea (shortness of breath)
- Chest pain or discomfort
- Confusion
What is bradycardia and why does it occur?

What are the dangers associated with bradycardia?
- Heart failure
- Fainting (syncope)
- Chest pain (angina pectoris)
- Low blood pressure (hypotension)
- High blood pressure (hypertension)
