How to check blood pressure and not just heart rate

Question edited for clarity, as I assume that you are talking about Blood Pressure and Heart Rate?

You can intentionally lower your blood pressure, and even easier to lower your heart rate.

You should always take best of three readings a couple of minutes apart. You should breathe deeply and relax. You blood pressure cuff should be level with the heart. If you are overweight, you should sit up straight as 'slumping' puts pressure on the heart.

Resting heart rate should be 72, but 60 to 100 is fine

Not enough information to answer safely.

A Blood Pressure of 67 makes no sense, as there are 2 numbers.
For example 150/90
The top number is the Systolic pressure, the pressure when your heart contracts.
The bottom number is the Diastolic pressure, the pressure when your heart relaxes.
Depending on many factors a bottom number of 67 may be very normal.
For example if you are a small elderly woman 67 would not be unusual.
Young athletes in excellent physical condition also have lower blood pressures.

I don't know why you went to the ER.
Nothing you have said so far indicates there was an emergency.

Were you having serious symptoms, or were you merely anxious and checking your blood pressure (or your pulse) by yourself.

I am wondering however if you mean pulse, i.e. heart rate, instead of "blood pressure".
A heart rate of 67 again might be very normal and not need to be changed.

I am thinking what they meant to say was that your blood pressure is 132 over 75 and your pulse is 75. Blood pressure has two readings, a high and a low one. If this is the case, your blood pressure is fine and your heart rate (the number of times your heart beats per minute) is also fine!

low blood pressure dangerous only if it causes
noticeable signs and symptoms, such as:
Dizziness or lightheadedness
Fainting (called syncope )
Dehydration and unusual thirst - Dehydration can sometimes
cause blood pressure to drop. However, dehydration does not
automatically signal low blood pressure. Fever, vomiting, severe
diarrhea, overuse of diuretics and strenuous exercise can all lead
to dehydration, a potentially serious condition in which your body
loses more water than you take in. Even mild dehydration ( a loss
of as little as 1 percent to 2 percent of body weight ), can cause
weakness, dizziness and fatigue.
Lack of concentration
Blurred vision
Nausea
Cold, clammy, pale skin
Rapid, shallow breathing
Fatigue
Depression
Low blood pressure can occur with:
Prolonged bed rest
Pregnancy - During the first 24 weeks of pregnancy, it's
common for blood pressure to drop.
Decreases in blood volume - A decrease in blood volume can
also cause blood pressure to drop. A significant loss of blood
from major trauma, dehydration or severe internal bleeding
reduces blood volume, leading to a severe drop in blood pressure.
Certain medications - A number of drugs can cause low blood
pressure, including diuretics and other drugs that treat
hypertension; heart medications such as beta blockers; drugs for
Parkinson's disease; tricyclic antidepressants; erectile dysfunction
drugs, particularly in combination with nitroglycerine; narcotics
and alcohol. Other prescription and over-the-counter drugs may
cause low blood pressure when taken in combination with HBP
medications.
Heart problems - Among the heart conditions that can lead to
low blood pressure are an abnormally low heart rate
(bradycardia ), problems with heart valves , heart attack and heart
failure . Your heart may not be able to circulate enough blood to
meet your body's needs.
Endocrine problems - Such problems include complications with
hormone-producing glands in the body's endocrine systems;
specifically, an under-active thyroid (hypothyroidism), parathyroid
disease, adrenal insufficiency (Addison's disease), low blood
sugar and, in some cases, diabetes.
Severe infection (septic shock) - Septic shock can occur when
bacteria leave the original site of an infection (most often in the
lungs, abdomen or ******* tract) and enter the bloodstream. The
bacteria then produce toxins that affect blood vessels, leading to
a profound and life-threatening decline in blood pressure.
Allergic reaction (anaphylaxis) - Anaphylactic shock is a
sometimes-fatal allergic reaction that can occur in people who are
highly sensitive to drugs such as penicillin, to certain foods such
as peanuts, or to bee or wasp stings. This type of shock is
characterized by breathing problems, hives, itching, a swollen
throat and a sudden, dramatic fall in blood pressure.
Neurally mediated hypotension - Unlike orthostatic
hypotension, this disorder causes blood pressure to drop after
standing for long periods, leading to symptoms such as dizziness,
nausea and fainting. This condition primarily affects young people
and occurs because of a miscommunication between the heart
and the brain.
Nutritional deficiencies - A lack of the essential vitamins B-12
and folic acid can cause anemia, which in turn can lead to low
blood pressure.
Severely low blood pressure can have underlying causes that may:
Be an indication of serious heart, endocrine or neurological
disorders
Deprive the brain and other vital organs of oxygen and
nutrients, ultimately leading to shock, which can be life
threatening

talk with your doctor as blood pressure readings vary between patients, weights , age and health conditions
always have your blood pressure done by the doctor as that will give a record of any variations that could be harmful
at this point it seems slightly high but the bigger concern is the diabetes and what ever the heart condition is
again consult with your doctor and get a proper diagnosis

Blood Pressure Blood pressure chart

Yes, little low. Normal is around 120/80mmHg. Rate is fine.. Normal is 70 at rest. Check placement of cuff and it is level with your heart

As a 30 year EMT, I think I can help you.

There's 2 numbers that make up your blood pressure. The top number is called the Systolic pressure. The bottom number is call the Diastolic pressure. When a blood pressure is taken, it's measuring the pressure that the heart is producing when it pumps blood through the arteries. For example, what's considered a normal blood pressure in a healthy individual is in the range of 120/80. Of course age, life style and other health conditions, play a role in what yours may be. A person with High blood pressure or Hypertension would have a blood pressure of over 160 - Systolic and over 90+ Diastolic. 90 is actually the borderline for hypertension. That's why I indicated 90+.

The other reading on your monitor is your heart rate or pulse rate. It's how many beats your heart completes in one minute. It also indicates an irregular heart beat by the showing a small LED window on the left of the screen adjacent to the Systolic pressure reading, It will say IHB. Any movement or shaking or talking during the measurement can result in pulse irregularities. So hold very still when taking your blood pressure. This irregularity by itself is not of much concern, unless it shows up frequently. In which case, you should seek medical advice.

That covers just about all there is to know about what the readings mean. Armed with this, you should be able to effectively monitor your blood pressure and pulse rate and report them to your doctor.

Hope I was able to help you understand how it works and what it's telling you. if so, please let me know, by rating my response to you. Thanks and have a healthy day.

Measuring your own blood pressure is an important way of monitoring your health. High blood pressure is a major health problem, which can be treated effectively once detected. Measuring your blood pressure between doctor visits on a regular basis in the comfort of your home, and keeping a record of the measurements, will help you to monitor any significant changes in your blood pressure. You should also keep an accurate record of your blood pressure, to help your doctor diagnose and possibly prevent any health problems in the future.
