5 things to avoid if you have a dicky heart
CAFFEINE
EVEN 50 to 300mg of caffeine (the amount in half a cup to three cups of coffee), can raise heart rates and blood pressure in many, even those without a heart rhythm problem.
‘If you already have a heart arrhythmia, it is best to moderate your intake of caffeine, which can also be found in sports drinks, chocolate and tea,’ says Philippa Hobson, a senior cardiac nurse at the British Heart Foundation.
Victoria Taylor, a senior dietitian at the British Heart Foundation, adds: ‘Studies suggest that up to five cups of coffee a day shouldn’t cause problems unless you are very sensitive to caffeine.’
COLD AND FLU CURES
SOME over-the-counter remedies contain caffeine and adrenalinetype stimulants, which can make your heart beat faster, says Philippa Hobson, who suggests sticking to simple remedies such as honey and lemon.
STRENUOUS EXERCISE
FOR most with heart arrhythmias, exercise is encouraged, including gym workouts. However, some weightlifters report heart palpitations when wielding heavy dumbbells.
There are only a few rare types of arrhythmia that can worsen with exercise.
‘A stress test can determine if you have an arrhythmia brought on by exercise,’ says cardiologist Professor Chris Gale.
‘Once you have had these tests, then you can work out a safe exercise plan.’
LACK OF POTASSIUM
NOT enough potassium in your diet — or too much — can cause electrical abnormalities in the heart cells and master pacemaker, because it interferes with the normal flow of molecules in and out of the cell which creates the heart’s electrical charge.
‘When you are diagnosed with a heart rhythm disorder, your doctor may order blood tests to check the electrolytes balance,’ says consultant pharmacist Helen Williams.
‘Magnesium, calcium and potassium all play a role in the heart’s electrical system.
‘If necessary, you will then be advised to change your diet.’
ROLLER COASTERS
THERE is a reason why many white-knuckle rides and roller coasters won’t admit people who have a heart condition.
‘These rides can cause a surge of adrenaline, and rapidly rising blood pressure, which can put undue stress on a heart already under strain,’ says Philippa Hobson. ‘You may find, sadly, that these rides are no longer suitable for you.’
