2. Fluttering Sensations
Premature beats that occur often or in rapid succession may cause a greater awareness of heart palpitations or a “fluttering” sensation in the chest or neck. Arrhythmias refer to abnormal beats or basically any alternation from the normal sequence of contract and pumping of blood. A fastened heart rate is normally referred to as a tachycardia (which refers to an adult heart that pumps more than 100 beats per minute), according to the American Heart Association.
Although arrhythmias are most likely harmless and don’t pose any threat, they can cause the heart to pump less effectively. This in turn, can impact almost every organ in the body that relies on fresh blood supply (i.e., the lungs) and ineffective function of organs can cause permanent damage over the long term.
