What to know about the heart rate during a heart attack
From the Medical News Today website
Someone’s heart rate can increase or stay the same during a heart attack. An elevated heart rate is not a specific sign or symptom of a heart attack.
Heart attacks involve a restriction or stoppage of blood flowing to the heart. A person’s heart rate during a heart attack will vary based on their overall health, medication use, and other medical conditions.
Some people will experience an increased heart rate during a heart attack, but others will not. More common signs of a heart attack include severe chest pain, shortness of breath, and tightness in the chest.
