Two articles on breath-holding spells [12] [13] strongly suggest that parents consider having their child be tested by electrocardiogram for the rare, but real possibility that the BHS episodes are actually a symptom of prolonged QT-syndrome, a serious but treatable form of cardiac arrhythmia.
This type of cry is characterized by the same temporal sequence as the basic pattern but distinguished by differences in the length of the various phase components. The third cry is the pain cry, which, unlike the other two, has no preliminary moaning. The pain cry is one loud cry, followed by a period of breath holding. [12]
[citation needed] Deliberate hyperventilation has been used by underwater breath-hold divers for the purpose of extending dive time as it effectively reduces respiratory drive due to low CO 2 levels. This allows one to break their standard limit of breath holding, at an increased risk of shallow water blackout (which is a significant cause of ...

Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep. It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1] Catathrenia begins with a deep inspiration.

It is different from a stertor, which is a noise originating in the pharynx. Stridor is a physical sign which is caused by a narrowed or obstructed airway.
Tolerance can in addition be trained. The ancient technique of free-diving requires breath-holding, and world-class free-divers can hold their breath underwater up to depths of 214 metres (702 ft) and for more than four minutes. [4] Apneists, in this context, are people who can hold their breath for a long time.
