But in certain forms of heart failure it may occur and becomes so marked that the patient's rest is disturbed during the period of increased breathing. This is preceded by a period when the breathing almost ceases or completely ceases; it may be for a period of half a minute to a minute during which the patient may fall asleep to be awakened up, it may be by a sense of suffocation; on its resumption the breathing is often exaggerated....
