What is Tachycardia
Tachycardia occurs when the heart beats faster than the normal resting heart rate. Typically, a healthy adult’s heart rate ranges from 60 to 100 beats per minute at rest. However, in cases of tachycardia, the heart rate in one or both chambers increases beyond this range.
The heart rate is regulated by electrical signals transmitted across heart tissues. Tachycardia occurs when abnormalities in the heart result in rapid electrical signals.
While some cases of tachycardia may present with no symptoms or complications, it can pose serious risks to heart function. It may increase the likelihood of stroke, sudden cardiac arrest, or even death.
What are the signs of tachycardia
When the heart rate accelerates, it may struggle to adequately circulate blood throughout the body, leading to potential oxygen deprivation in organs and tissues. This can manifest in various signs and symptoms associated with tachycardia, including:
– Dizziness
– Shortness of breath
– Lightheadedness
– Rapid pulse rate
– Heart palpitations
– Chest pain
– Fainting
In certain instances of tachycardia, individuals may not experience any symptoms, and the condition may only be detected during a physical examination or through cardiac monitoring tests such as an electrocardiogram.
What is the expected outcome of tachycardia
The long-term outlook for tachycardia is generally positive when it stems from causes such as fever, blood loss, hypertension, medication, or dietary factors. Tachycardias associated with heart or lung issues can often be managed effectively with medication or various procedures.
