There are many causes of vomiting (See Table 1: Causes, Diagnosis and Treatment of Vomiting in Dogs). It is important to determine the cause so the appropriate treatment can be given.
Pulse rates vary from person to person. The normal pulse rate for humans is usually 60 to 100 beats per minute, however, there are certain medical conditions such as cardiac arrhythmia which may alter the normal pulse rate of an individual. Other influencing factors include your age, gender and fitness level.
The highest pulse rate for any individual is 220 bpm minus your age. A healthy person should achieve a pulse rate of 60 to 80 percent of this value during or after exercising. Hence for a person who is 50 years old, the desired pulse rate is calculated as follows 220-50=170 bpm. This means the fastest pulse rate you should have at age 50 is 170 beats per minute.
