[Exercise tests in spirometry].

Actual situation: There is a great variety of exercise programs (formerly called protocols) used in daily routine and general practice. Exercise programs vary with increments, step-duration, speed and grade, although standard recommendations have been published recently. In the USA, the Bruce program is widely accepted, although some criticism has been published. Comparing different exercise programs it is obvious, that maximal values (VO2, heart rate etc.) are only moderately affected by the program, but submaximal values are strongly influenced by the methodological procedure. Advantages and disadvantages of the different exercise testing procedures will be presented. As we need some standardized exercise programs to avoid "free-style ergometry", recommendations may be based on the following assumptions: Exercise testing should not be too short nor too long (10-12 min total test time), work rate increments should be intermediate (adapted to physical fitness), work rate steps should be about 2 min or an individualized ramp test should be used. Exercise test programs have to be selected according to the patient's fitness, to the disease or function to be studied, and to the laboratory setting. Standardization is strongly recommended.

[Anti-arrhythmia therapy in emergencies--lidocaine versus ajmaline].

Up to now lidocain was regarded as remedy of first choice in life-threatening ventricular arrhythmias. According to more recent investigations in the emergency situation ajmalin showed itself superior to lidocain in the treatment of ventricular tachycardias. For the prophylaxis of primary ventricular fibrillation lidocain is still recommended, though despite numerous studies an effectiveness is not verified. The treatment of the primary ventricular fibrillation should always be performed by defibrillation as far as possible. The earlier it is performed the more successful is the measure. If a defibrillator is not at disposal an attempt with lidocain or ajmalin can bie made.

Use of inotropes in the critical care setting.

Positive intropic agents are widely used in critical care settings to treat several syndromes associated with hemodynamic derangements. Norepinephrine, epinephrine, dopamine, and dobutamine are the drugs of choice for several specific critical care syndromes, but the properties of each agent and the pathophysiology of the patient are important mediating factors. The hemodynamic status of the patient should be assessed, with invasive hemodynamic monitoring if necessary, and the choice of drug should be made on the basis of data thus obtained.
