This pattern is similar to Heart Yang Deficiency, but much severe. Therefore the clinical symptoms are quite similar. The key different manifestation is the cyanosis of the lips. It is because the Blood flow are impaired due to lacking of Yang Qi's moving force.
Coma happens in rare severe cases. It is because the Heart should house the Mind. However, the Mind has no 'residence' due to the overall collapse of Heart Qi. In this case, the patients might not even be able to move their tongue due to lack of Qi. Also, Yang Deficiency leads to internal Coldness which contracts the tongue muscles. Therefore, the tongue can not be moved out of mouth.
The Hidden pulse shows the severe degree of Yang Deficiency. It is an extreme case of the Deep pulse. The Knotted pulse also shows the severe Yang Deficiency, because the Heart has not enough energy to function properly.
Precursor patterns: Heart Yang Collapsing can derive from Kidney Yang Deficiency
Excessive sexual activity: Since Heart Yang Collapsing always develops from severe Kidney Yang Deficiency, excessive sexual activity indirectly causes Heart Yang Collapsing since it causes the latter.
Overwork over a long period of time : Since Heart Yang Collapsing always develops from severe Kidney Yang Deficiency, overwork over a long period of time indirectly causes Heart Yang Collapsing since it causes the latter.
Chronic illness: Since Heart Yang Collapsing always develops from severe Kidney Yang Deficiency, chronic illness indirectly causes Heart Yang Collapsing since it causes the latter.
Emotional problems such as sadness or grief: Emotional problems, particularly from sadness or grief, can lead to Heart Yang Deficiency
Blood loss: Any severe or prolonged blood loss will cause Heart Blood Deficiency, which, in turn, will lead to Heart Yang Deficiency.
Diagnosing a pattern in Chinese Medicine is no easy feat and should be left to professional practitioners. In particular one has to know how to differentiate between different types of pulses and tongue coatings, shapes and colors as well as learn to read from a long list of seemingly unrelated symptoms.
