Final answer:
Arrhythmias are more commonly found with unstable angina, which is a serious condition that could precede a heart attack and requires immediate medical attention. Treatment could involve medication or the use of a pacemaker or defibrillator to normalize the heart rhythm.
Step-by-step explanation:
Arrhythmias can be present in various types of angina, but they are more commonly associated with unstable angina. Unstable angina is a serious condition that can lead to an imminent heart attack and represents a medical emergency. It is characterized by chest pain that occurs at rest, can last more than 15 minutes, and maybe a new occurrence. These symptoms differ from stable angina, which typically occurs with exertion and improves with rest or medication. Arrhythmias related to unstable angina are due to problems with the heart's electrical conduction system, which can significantly affect the heart's ability to pump blood effectively.
Treatment of these arrhythmias may include medications, or in severe cases, the implantation of a pacemaker or a defibrillator to maintain a normal heart rhythm. Unstable angina is a more serious type of angina where pain occurs during rest, lasts longer than 15 minutes, and is of new onset. Arrhythmias are abnormal heart rhythms, and they can occur in unstable angina due to problems with the electrical conduction system of the heart.
