Can impaired heart function cause dizziness? On what basis?

Impaired heart function will cause dizziness, this is because the new function is damaged when the heart pumping will be reduced, at this time will also lead to the heart's pumping function will be reduced, resulting in myocardial necrosis, and will also lead to a decrease in the contractility of the myocardium, so the reduction of heart snow will lead to insufficient cerebral blood supply, at this time the patient will appear dizzy, and myocardial damage will also cause arrhythmia, at this time will affect the heart's conduction system, and then cause the patient to have atrioventricular block, and then the patient has dizziness and rapid heartbeat, which can cause dizziness in severe cases. <>

Heart function impairment will have a serious impact on themselves, I wish you must actively prevent it in your daily life, patients must reduce their own tension in life, otherwise it will have an overload on the heart, and in daily life Patients should also actively exercise their own body, which helps to increase the heart's capacity, and patients should maintain good living habits in life, eat some light food, and reduce the frequency of staying up late, Maintain a positive and optimistic attitude, patients with heart disease should go to the hospital for regular check-ups, and at the same time, they should also be examined by doctors to determine whether their heart has other lesions, and the most important point is to maintain emotional stability and strengthen the protection of the heart. <>

Heart function impairment is still relatively harmful to people, sometimes long-term myocardial damage will cause heart defects and hypoxia and myocardial lesions, etc., and in severe cases, it will cause patients to have heart failure and heart rate disorders, and at the same time, it will be easy to occur sudden death, which is easier to threaten the life safety of patients, and if patients do not get timely treatment, there will be heart failure and arrhythmia leading to sudden cardiac arrest, which will accelerate people's death. Moreover, once people's scheming is damaged, it will also bring some other sequelae and complications. <>

Heart failure can cause dizziness in patients, because most patients with heart failure have weak heart function, which can easily lead to insufficient perfusion of brain tissue, thereby causing ischemia and hypoxia in the brain, so it is manifested as dizziness.

It can cause dizziness because the most important pump in the blood circulation, if abnormal, can cause a lack of blood supply to the brain leading to dizziness.
