Jason Howland, moderator: Some symptoms that you might expect for heart arrhythmia are often red flags for seeking treatment or screening.
Elijah Behr, M.D., Cardiovascular Disease Mayo Clinic Healthcare in London: If a symptom is serious — so a sudden collapse or
loss of consciousness — that's immediate attendance to an emergency department. Likewise, if one's having palpitations — so the heart racing
away unexpectedly — and associated dizziness, lightheadedness, another reason to go to the emergency department straightaway.
Jason Howland: Chest pain also can be an obvious sign and may require emergency care.
Some heart palpitation symptoms may be less frequent and severe, but still should be assessed by a health care clinician.
Elijah Behr, M.D. The other thing that's a red flag, in particular in young patients, is if there's a family history of concern. Accepting that that person may not have any history of heart problems themselves already, if they know that there is a family history of somebody at a young age having had a premature or sudden death, or if there's a family history of inherited heart problems, then that may flag up that there is a potential risk if somebody is having symptoms or may actually just need screening from the point of view of preventing risk before they develop symptoms.
