Synchronous diaphragmatic flutter (SDF) SDF, commonly known as ‘
thumps
‘, is the synchronous contraction of the diaphragm with the heart beat.
What cause synchronous diaphragmatic flutter?
Synchronous diaphragmatic flutter (SDF), or “thumps,” arises
when fluid and electrolyte imbalances disrupt the membrane potential of the phrenic nerve
. The phrenic nerve begins to discharge in concert with atrial depolarization with subsequent contraction of the diaphragm.
What is the common English word for a synchronous diaphragmatic flutter?
Hiccup
. A hiccup is an involuntary contraction of the diaphragm that may repeat several times per minute. In medicine, it is known as synchronous diaphragmatic flutter, or singultus, Latin for the act of catching one’s breath while sobbing.
What is synchronous diaphragmatic flutter in horses?

due to firing of the phrenic nerve in synchrony with atrial depolarization
, causing the diaphragm to contract with each heartbeat. This occasionally produces an audible thumping sound.
What are horse thumps?
Also called synchronous diaphragmatic flutter, thumps is generally observed in fatigued horses, especially those that have sweated profusely during a bout of prolonged exercise. … In severe cases, convulsions are so extreme that a thumping noise is produced, hence the name.
What is a single hiccup called?
The afferences are essentially the inspiratory muscles and the pharyngo-larynx. When the single hiccup becomes repetitive, it can be brief (less than 48 h) and is called “
acute hiccup”
(a frequent benign condition).
Can you hiccup in your sleep?
Sleep
synchronizes the breathing rate with the hiccupping rate. During light sleep, the Hc rate exceeds the breathing rate, whereas during deep sleep, the breathing rate exceeds the Hc rate.
Why do I keep hiccuping so much?
Nerve damage or irritation
A cause of long-term hiccups is
damage to or irritation of the vagus nerves
or phrenic nerves, which serve the diaphragm muscle. Factors that may cause damage or irritation to these nerves include: A hair or something else in your ear touching your eardrum. A tumor, cyst or goiter in your …
Why do horses tremble?
The purpose of the muscle vibration is
to generate heat and raise body temperature
. However, horses will also sometimes shiver if they have a fever, are stressed, are experiencing abdominal pain (colic), or are recovering from anesthesia.
Why is my horse’s muscle twitching?
Localized muscle twitching is often seen with
electrolyte imbalance
, local nerve injuries, certain neurologic and muscular diseases, and a variety of other conditions.
Are electrolytes good for horses?
In fact, electrolytes are
needed for almost all bodily functions
, including fluid regulation and balance, digestion, the acid-base (pH) status of the horse and vital neurological functions such as muscle contraction for optimum performance. … Electrolytes are lost from the body in urine and faeces and through sweat.
How do you prevent muscle tremors in horses?
If a horse has both PSSM and Shivers, owners have reported improvements in their horses by feeding a diet high in fat and low in starch. This does not appear to cure horses from Shivers but it may reduce the frequency of muscle spasms. Adequate
levels of vitamin E and Selenium
are important in the diet.
How can you tell if a horse is dehydrated?
Check the
Mucous Membrane
Give the inside of your horse’s upper lip
a swipe. It should feel moist with saliva and shiny. Colors such as white or purple on its mucous membrane indicate signs of dehydration. But if it begins to feel dry and the eyes look sticky, this may be a sign of dehydration.

- Hold (X) and use LEFT STICK to bank left/right and survive turns.
- Hold (X) to slide through red bars without damage.

- Boss patterns loop until you defeat them.
How do you stop a horse from hiccuping?
Treatment and Prevention
A mild case of thumps often goes away on its own after rest, rehydration, and replenishment of electrolytes. More severe cases – or situations where the horse is exhausted and dehydrated – need
immediate veterinary intervention
.
