[Effect of ergonovine and the cold stress test on time intervals of left ventricular systole and their significance for the diagnosis of coronary heart disease].

In 20 healthy test persons and 44 patients with a coronary heart disease without stenocardia at rest the ergonovine and the cold pressure test were performed. During the tests the ECG in 12 standard leads and the mechanocardiogrammes were registered, from which the time intervals of the left-ventricular systole were calculated. From the analysis of the pectanginous complaints and/or from the changes of the ST segment for the diagnosis of the coronary heart disease a sensitiveness of the ergonovine test of 40% was obtained, whereas the sensitiveness of the cold tolerance test was only 10%. In healthy test persons during the ergonovine test a shortening of Q-1, a decrease of the quotient PEP/LVET and a prolongation of LVETI were established. Apart from this, in patients with coronary heart disease also shortenings of ICT and PEP and an increase of the quotient LVET/S1S2 were made evident. During the cold tolerance test in healthy test persons, besides the prolongation of LVETI, no other changes were stated. On the other hand, in the patients a decrease of the quotient PEP/LVET and a shortening of PEP were existing. The diagnostic value of the analysis of the left-ventricular time intervals was insignificantly higher during the ergonovine test than at rest. However, during the cold pressure tests no differences were stated. The application of the analysis of the left-ventricular time intervals does not essentially enlarge the sensitiveness of the two tests in comparison to the analysis of the changes of the ST segment in the ECG.

[Esophageal precordial cardiac stimulation in the diagnosis of ischemic heart disease].

The esophageal atrial cardiac stimulation was applied to 93 patients divided into 4 groups: patients with typical, probable and atypical angina pectoris and clinically healthy controls. The tests positive for ischemic heart disease are classified into 3 classes according to the duration of ECG ischemic changes: I class--the ischemic changes are registered during the time of the test only; II class--the changes are seen in the first ECS complexes after the stimulation and III class--the changes persist after the second minute following the esophageal atrial stimulation. The test was worked out to diagnostic criteria in 92.5% of the cases and is undoubtedly positive in 77.5% of the patients with typical and probable stenocardia and in 36.6% of the patients with atypical precordial pain. Most important for the diagnosis of ischemic heart disease are: the early occurrence of ST-depression before the submaximal pulse rate is reached, registration of II and III degree of ST-depression and the appearance of chest pain during the time of the test. The esophageal atrial stimulation is a valuable method for the diagnosis of ischemic heart disease and it is surprisingly easy to perform. The method is harmless and can be applied to patients to whom the physical exercise test cannot be applied.

Patient with coronary artery spasm and role of the critical care nurse.

Review of the literature reveals that coronary artery spasm exhibits a wide variation in clinical presentation. This variation makes accurate diagnosis and management difficult; however, precise diagnosis is essential so that appropriate therapy can be given. Critical care nurses are in an excellent position to assess patient findings that may help suggest or exclude the presence of coronary artery spasm as the cause of the myocardial ischemia. Critical care nurses also can play an important part in suggesting and carrying out appropriate management of coronary artery spasm.

Exercise-induced intermittent angina and ST-segment elevation in Prinzmetal's angina.

A patient with primary angina showed intermittent ST elevation (with and without chest pain), during two exercise tests performed on consecutive days; the same ST changes were also seen during the recovery phase. The electrocardiographic changes recorded in this patient may be considered an example of myocardial response to spasm-related ischemia.

[Prinzmetal's syncopal angina during an electroencephalogram. Triggering role of the hyperpnea test].

We are reporting a cardiac arrest occurring during an electroencephalogram with hyperventilation. The diagnosis is made on the Holter recording which shows a Prinzmetal's angor tracing followed with ventricular arrhythmias, leading to asystoly. The physiopathology of the spasm is not clear and we are discussing the possible mechanisms. We stress again the harmful role of beta-blockers in this pathology. In addition, we insist on electrocardiographic manifestations surrounding sudden death. As for the hyperventilation test, its potential risks call for caution during its performance.

[Comparison of the effects of bepridil and diltiazem in Prinzmetal's angina. Crossed, randomized, double-blind study. Apropos of 14 cases].

The efficacy of bepridil was compared with that of diltiazem in treatment of Prinzmetal's angina, in a crossed, randomized double-blind study of 14 observations using repeated Holter recordings (a total of 9 for each patient). Clinical and electrical monitoring showed that the efficacy of bepridil is comparable to that of diltiazem in treatment of spastic angina.
