Arnica
Acute attack of Angina Pectoris.

Digitalis. [Dig]
Pulse slow, but primarily strong, there is great weakness of the cardiac tissue, and, secondarily, the pulse becomes weak. Extra exertion increases its rapidity, but diminishes its force, so that the quick pulse becomes irregular and intermittent. This irregular intermittency is a marked symptom. The heart feels as if the blood stood still. There is weakness and numbness of the left arm, and often blueness of the surface of the body, or cyanosis. The patient fears that the heart will stop beating if he should make any motion. This uneasy feeling about the chest rarely amounts to real pain.

Cactus grandiflorus. [Cact]
“Sensation as if the heart were grasped with an iron hand,” which clutches and relaxes alternately, is ever present to the mind. It should be borne in mind that not all patients express themselves alike. A squeezed sensation may mean the same symptom. Pains shooting into the left arm, oedema and a quick, throbbing, tense, hard pulse, which may or may not intermit. Carditis and pericarditis may call for Cactus. It presents a better picture of rheumatic carditis than any other remedy. Angina Pectoris with severe constriction, suffocation, cold sweats, give mother tincture 10 drops in water every 30 minutes till condition stabilizes.

Glonoine
Arterial spasm with temporary loss of consciousness. Heart Attack. Mother tincture 15 drops every few minutes.

Spigelia. [Spig]
Acute carditis and pericarditis. There are sharp pains shooting from the heart to the back, and radiating from the heart down the arm, over the chest, and down the spine. There is palpitation worse from any movement of the arm or body. There is a purring sensation felt over the cardiac region when placing the hand thereon. The pulse is intermittent, not synchronous with the heart beat, and the slightest motion of the arm or hands makes the patient worse. Heart symptoms accompanying neuralgia. Irregular and tumultuous action of the heart, at times the heart beat is even audible.
